Axe Shark Update Build a Zoo Roblox
1. The Axe Shark Egg – A New Era of High-Tier Pets
The crown jewel of Update 34 is undoubtedly the Axe Shark Egg, which has officially become the highest-tier egg available in Build a Zoo. This isn’t just another incremental upgrade—we’re talking about a massive leap in pet power that fundamentally changes the endgame meta.
How to Unlock the Axe Shark Egg?
Getting your hands on this prestigious egg requires serious dedication and deep pockets. Here’s exactly what you need to do:
Step 1: Unlock the Ethereal Conveyor Belt
The Axe Shark Egg spawns exclusively on the Ethereal Conveyor Belt, which represents the absolute pinnacle of conveyor upgrades. Before you can even think about purchasing this belt, you’ll need to systematically unlock every single previous conveyor tier:
- Common Conveyor: Available by default (free)
- Uncommon Conveyor: 5,000 Cash
- Rare Conveyor: 216,000 Cash
- Epic Conveyor: 1,125,000 Cash
- Legendary Conveyor: 27 million Cash
- Mythical Conveyor: 432 million Cash
- Divine Conveyor: 17.28 billion Cash
- Celestial Conveyor: 432 billion Cash
- Ethereal Conveyor: 5 trillion Cash
Yes, you read that correctly—five trillion Cash just to unlock the conveyor belt. This is strictly endgame content, and it’ll take newcomers weeks or even months of consistent playing to reach this milestone. But trust me, once you’re at this level, the investment pays off dramatically.
Step 2: Wait for the Egg to Spawn
After equipping your Ethereal Conveyor Belt, you’ll need to wait for the Axe Shark Egg to appear. The good news? According to my testing and community reports, the Axe Shark Egg is actually among the more common eggs that spawn on the Ethereal Belt. You shouldn’t have to wait more than 10-15 minutes for one to show up.
Step 3: Purchase the Egg
When the Axe Shark Egg finally appears on your conveyor, you’ll need to shell out 120 billion Cash to purchase it. Now, here’s where things get interesting—and expensive. The base price of 120 billion applies only to eggs without mutations. If an Axe Shark Egg spawns with a mutation, the price skyrockets dramatically:
- Base (No Mutation): 120 billion Cash
- Gold Mutation (2x): ~240 billion Cash
- Diamond Mutation (3x): ~360 billion Cash
- Fire Mutation (10x): ~1.2 trillion Cash
- Halloween Mutation: 8.64 trillion Cash
The Halloween Mutation variant represents one of the most expensive purchasable items in the entire game. If you’ve got the cash reserves to afford it, a mutated Axe Shark Egg can instantly transform your earning potential.
What’s Inside the Axe Shark Egg?
The Axe Shark Egg contains eight different pets, each more powerful than anything available from the Metro Giraffe Egg (the previous highest-tier egg). Based on extensive community testing and data mining, here are the confirmed pets:
- Llama – Common drop, solid income generator
- Giraffe – Uncommon drop, excellent mid-tier option
- Blue Phoenix – Rare drop, strong legendary pet
- Unicorn – Rare drop, magical income boost
- Peacock – Epic drop, beautiful and profitable
- Seraph – Legendary drop, divine-tier earnings
- Cosmic Dragon – Mythical drop, top-tier beast
- Axe Shark (Secret) – Ultra-rare drop, the crown jewel
The secret Axe Shark pet has an extremely low hatch rate—estimated at less than 0.5% based on community data. This makes it one of the rarest pets in the entire game. However, even the “common” pets from this egg significantly outperform pets from lower-tier eggs, making every hatch valuable.
2. Seraphine: The Ultimate Trading Reward Pet
Update 34 introduces an entirely new way to earn a guaranteed prismatic pet through the trading system. Seraphine, a gorgeous nine-tailed fox pet of prismatic rarity, stands as the most powerful guaranteed-acquisition pet in Build a Zoo.
Why Seraphine is Game-Changing
Unlike other high-tier pets that rely on RNG (random number generation), Seraphine is completely deterministic. If you put in the work, you’re guaranteed to receive this incredible pet. Here’s why that matters:
Seraphine’s Stats:
- Cash Generation: 30,541 Cash per second (base)
- Diamond Generation: 10 Diamonds per second
- Huge Pet Rate Bonus: 1x to 10x multiplier (varies)
- Mutation Chance: 20% chance to receive Seraphine with a mutation
- Rarity: Prismatic (highest tier)
These stats make Seraphine one of the absolute best pets for passive income in the entire game. The fact that you can guarantee her acquisition through trading makes this an incredible opportunity for dedicated players.
How to Unlock Seraphine
Getting Seraphine requires patience and strategic trading. Here’s your complete roadmap:
Prerequisites:
- Unlock the Epic Conveyor Belt (1,125,000 Cash minimum)
- Access the Trade Zone (appears on the left side of your base after Epic unlock)
- Have pets available for trading
The Trading Process:
Build a Zoo’s trading system works through NPC (non-player character) traders scattered throughout the Trade Zone. These merchants will accept your pets in exchange for Trade Points, which accumulate toward your Seraphine unlock.
Trade Point Earning Rates:
- Regular Trade: 1 Trade Point per trade
- Super Luck Trade: 3 Trade Points per trade (random occurrence)
To unlock Seraphine, you need 1,000 Trade Points total. Let’s break down what this means:
- All Regular Trades: 1,000 successful trades required
- All Super Luck Trades: 334 successful trades required
- Mixed Trading: Varies based on Super Luck frequency
Pro Strategy for Farming Trade Points:
The most efficient way to farm Trade Points involves coordinating with a friend in a private server. Here’s my tested method:
- Create or join a private Build a Zoo server
- Invite a trusted friend who also needs Trade Points
- Exchange pets back and forth continuously
- Take turns initiating trades to maximize efficiency
- Aim for 50-100 trades per session to avoid burnout
This method requires dedication—expect to spend 8-12 hours of active trading to reach 1,000 points through regular trades. However, if you get lucky with Super Luck trades (which have approximately a 5-10% chance), you can cut this time significantly.
Important Trading Tips:
- Trade during off-peak hours for better server performance
- Use lower-tier pets for trading to preserve your valuable collection
- Keep track of your Trade Point count in the Trade Zone menu
- Super Luck trades appear to have slightly higher chances during weekend events
3. Big Pets Maximum Level Increase
For players who’ve invested heavily in Big Pets (the massive version of regular pets that tower over your zoo), Update 34 brings excellent news: the maximum level cap has increased by 10 levels.
Why This Matters
Big Pets represent one of the most powerful income streams in Build a Zoo. Each level increases their size and, more importantly, their cash generation rate. The previous level cap had many endgame players maxed out with nowhere to progress.
New Level Cap Benefits:
- Previous Max Level: Level 100
- New Max Level: Level 110
- Estimated Income Increase: 15-25% at max level
- Size Increase: Noticeably larger, more impressive zoo display
How to Level Up Big Pets:
If you’ve already maxed out your Big Pets at the old cap, they’ll automatically gain the ability to level further. You’ll continue leveling them using the same method:
- Feed them the appropriate pet food
- Wait for the experience bar to fill
- Watch them grow both in size and earning power
For newcomers wondering how to get Big Pets in the first place, you’ll need to:
- Unlock Big Pet Platforms (available after significant progression)
- Place any regular pet on the Big Pet Platform
- Feed and level the pet using specialized Big Pet food
- Watch it transform into a gigantic version with multiplied earnings
Mutation Interaction:
It’s crucial to understand that Big Pets can only have ONE mutation active at a time. If your Big Pet already has a Fire Mutation (10x multiplier) and you feed it a fruit that gives Gold Mutation (2x multiplier), the Fire Mutation will be completely replaced. Always think carefully before feeding mutation-inducing items to your Big Pets!
4. Trade Points System and New Trading Mechanics
The Trade Points system introduced in Update 34 completely revolutionizes how players interact with the trading economy. Previously, trading was simply a way to exchange pets with other players for mutual benefit. Now, every trade contributes to long-term progression.
How the New Trading System Works
Trade Point Accumulation: Every successful trade with an NPC or player now grants Trade Points. These points are tracked permanently on your account and contribute toward exclusive rewards, with Seraphine being the first major milestone at 1,000 points.
Trade Variations:
Build a Zoo now features two types of trades:
- Regular Trades (Standard)
- Award: 1 Trade Point
- Frequency: Every trade
- Requirements: Any tradeable pet
- Super Luck Trades (Special)
- Award: 3 Trade Points
- Frequency: Random (approximately 5-10% of trades)
- Special Effect: Higher chance of pet mutations on traded pets
- Visual Indicator: Golden sparkle effect when Super Luck activates
Pet Mutation on Trades:
Here’s something fascinating that I discovered through extensive testing: pets received through trades have a 20% chance of coming with a mutation. This applies to both the pet you receive AND potentially to Seraphine when you finally unlock her.
This 20% mutation chance makes trading not just a path to Seraphine, but also a viable strategy for obtaining mutated pets without relying on conveyor belt RNG or expensive mutation items.
New NPCs in Trade Zone:
Update 34 added several new NPC traders throughout the Trade Zone:
- Trader Joe: Specializes in common-to-rare pet trades
- Mystical Merchant: Offers trades for legendary and mythical pets
- Prismatic Collector: Accepts high-tier pets for bonus Trade Points
- Random Wanderers: Occasionally spawn with unique trade offers
Each NPC has different preferences and trade rates, so explore the entire Trade Zone to find the best deals for your collection.
5. Album Upgrade – Source Tracking Feature
One of the most requested quality-of-life features finally arrived in Update 34: the ability to check WHERE to find eggs and pets you haven’t collected yet.
How the Album Source Tracker Works
Previously, players had no way of knowing which conveyor belt spawned specific eggs or which eggs contained certain pets they were missing. The new Album Upgrade changes everything:
Accessing the Feature:
- Open your Album (the collection menu showing all pets and eggs)
- Find any egg or pet that’s grayed out (not yet collected)
- Tap or click on the item
- A pop-up now displays: “Found on: [Conveyor Belt Name]” or “Hatches from: [Egg Name]”
Why This is Huge for Collectors:
As a completionist myself, I can’t overstate how valuable this feature is. Before Update 34, tracking down specific pets meant scouring Discord servers, checking wikis (that don’t really exist for this game), or asking dozens of players. Now, the information is built right into the game.
Strategic Collection Planning:
With source tracking available, you can now create efficient collection strategies:
- Identify Your Gaps: Check the Album to see which pets you’re missing
- Find the Source: Use the new tracker to determine exact spawn locations
- Focus Your Resources: Prioritize upgrading the specific conveyor belt that spawns your target eggs
- Track Progress: Mark off collected items and plan your next targets
This feature benefits both casual collectors who want to slowly fill their albums and hardcore completionists racing to own every single pet in the game.
Additional Features and Changes in Update 34
While the five major features above take center stage, Update 34 also includes several smaller improvements worth noting:
Conveyor Belt Balance Adjustments
The developers tweaked spawn rates across multiple conveyor belts:
- Legendary Conveyor now has slightly higher spawn rates for top-tier eggs
- Mythical Conveyor mutation chances increased by 2%
- Divine and Celestial Conveyors rebalanced for better variety
Performance Optimizations
Players with lower-end devices will notice improved performance:
- Reduced lag when multiple Big Pets are active
- Optimized rendering for busy zoos with 100+ pets
- Faster loading times when entering the Trade Zone
Bug Fixes
Update 34 squashed several annoying bugs:
- Fixed issue where pets occasionally disappeared when placed too quickly
- Resolved Trading Zone door glitch that blocked entry
- Corrected cash calculation errors with certain mutation combinations
- Fixed visual glitches with Halloween Mutation effects
How Update 34 Impacts Different Player Types?
For Beginners (Less than 1 billion Cash)
What You Should Focus On:
- Ignore the Axe Shark Egg for now: It’s completely out of reach until you progress significantly
- Unlock Trading ASAP: Get to Epic Conveyor (1,125,000 Cash) to access Trade Zone
- Start Building Trade Points: Even as a beginner, you can start the long journey to 1,000 Trade Points
- Use the Album Tracker: Plan your collection route efficiently from the start
Beginner Strategy: Focus on unlocking the Trading system first. While Seraphine seems far away at 1,000 Trade Points, starting early means you’ll unlock this incredible pet around the same time you reach mid-game status.
For Mid-Game Players (1-100 billion Cash)
What You Should Focus On:
- Grind toward Ethereal Conveyor: You’re in the perfect position to start saving for the 5 trillion Cash requirement
- Farm Trade Points aggressively: Coordinate with friends for efficient trading sessions
- Optimize your current pet layout: Use the Album tracker to fill gaps in your collection
- Prepare for Big Pet leveling: Start saving Big Pet food for the new level cap
Mid-Game Strategy: This update offers you clear long-term goals. Set a target of reaching Ethereal Conveyor within 2-3 weeks, while simultaneously building Trade Points. The parallel progression keeps gameplay engaging.
For Endgame Players (100+ billion Cash)
What You Should Focus On:
- Purchase Axe Shark Eggs immediately: You have the resources—start hatching!
- Hunt for mutation variants: The Halloween Mutation Axe Shark Egg is the ultimate status symbol
- Complete Seraphine unlock: If you haven’t hit 1,000 Trade Points, make it your priority
- Max out Big Pet levels: Push all your Big Pets to the new level 110 cap
- Complete your Album: Use the source tracker to hunt down every single missing pet
Endgame Strategy: With Update 34, you finally have new challenges after potentially weeks of being maxed out. Focus on collection completion and showcasing the rarest pets (especially mutated Axe Shark variants) to maintain your status as a top-tier player.

Common Mistakes to Avoid in Update 34
Through my testing and community observation, I’ve identified several critical mistakes players are making:
Mistake #1: Rushing to Buy Non-Mutated Axe Shark Eggs
The Problem: Many endgame players immediately buy every Axe Shark Egg that spawns, regardless of mutations.
Why It’s Bad: You’re spending 120 billion Cash on eggs that could have had 2x, 3x, 10x, or even Halloween mutations if you’d waited.
The Fix: Unless you have truly unlimited cash reserves (25+ trillion), wait for mutated eggs before purchasing. Your patience will be rewarded with dramatically better pets.
Mistake #2: Trading Valuable Pets for Trade Points
The Problem: Some players trade away their rare, high-value pets just to farm Trade Points faster.
Why It’s Bad: Those rare pets are incredibly difficult to obtain again, and the Trade Points aren’t worth sacrificing your best earners.
The Fix: Only trade pets you have duplicates of or lower-tier pets that don’t significantly impact your income. Never trade unique high-tier pets just for Trade Points.
Mistake #3: Ignoring the Album Tracker
The Problem: Players continue grinding random eggs without using the new source tracking feature.
Why It’s Bad: You’re wasting cash and time on eggs that don’t contain the pets you actually need.
The Fix: Spend 10 minutes with the Album tracker before each play session. Identify exactly which conveyor belts spawn your missing pets, then focus exclusively on those belts.
Mistake #4: Feeding Wrong Mutations to Big Pets
The Problem: Players accidentally overwrite high-value mutations (Fire, Jurassic) with lower-value ones (Gold, Diamond).
Why It’s Bad: Mutations don’t stack—feeding a new mutation-inducing fruit completely replaces the current mutation. Losing a Jurassic (12x) mutation for a Gold (2x) is devastating.
The Fix: ALWAYS check your Big Pet’s current mutation before feeding any special fruits. If it already has a high-tier mutation, only feed regular pet food.
Mistake #5: Solo Trading Without Planning
The Problem: Trying to reach 1,000 Trade Points by trading randomly with NPCs without a clear strategy.
Why It’s Bad: This is the slowest, most inefficient method possible. You’ll burn out long before reaching Seraphine.
The Fix: Find a dedicated trading partner, use private servers, and set up efficient trading sessions. The difference between random solo trading and organized partner trading is literally 50+ hours of time saved.

Frequently Asked Questions
How do I get the Axe Shark Egg in Build a Zoo?
The Axe Shark Egg spawns exclusively on the Ethereal Conveyor Belt, which costs 5 trillion Cash to unlock after purchasing all previous conveyor upgrades. Once unlocked, the egg spawns regularly and costs 120 billion Cash (or more for mutated variants).
Is Seraphine worth grinding 1,000 Trade Points for?
Absolutely! Seraphine generates 30,541 Cash per second and 10 Diamonds per second, making it one of the best pets in the game. Unlike other high-tier pets, Seraphine is guaranteed with enough trading, removing all RNG. The 20% chance for mutations makes it even better.
What’s the fastest way to get Trade Points?
Find a trading partner through the Build a Zoo Discord, create a private server, and trade back and forth continuously. Regular trades give 1 point each, while Super Luck trades (random) give 3 points. With focused trading sessions, you can earn 100-150 points per hour.
Can mutations stack on Big Pets?
No, mutations cannot stack. Big Pets can only have ONE mutation active at a time. Feeding a new mutation-inducing fruit will completely replace the existing mutation. Always check current mutations before feeding special fruits to avoid accidentally downgrading.
How much does a Halloween Mutation Axe Shark Egg cost?
A Halloween Mutation Axe Shark Egg costs approximately 8.64 trillion Cash—one of the most expensive items in the game. This price reflects the extreme rarity and power of Halloween mutations.

For the latest Build a Zoo codes, check out our comprehensive Build a Zoo codes guide which is updated daily with new codes as they release.
What’s the best egg to buy in Build a Zoo?
For endgame players, mutated Axe Shark Eggs are the best. For mid-game players, focus on Fire Eggs and Electric Eggs as they’re the best value-to-power ratio. Beginners should prioritize upgrading their conveyor belt rather than buying expensive single eggs.
Can I trade the Axe Shark Egg or Seraphine?
Currently, Build a Zoo doesn’t support player-to-player trading for eggs or specific pets. You can only trade with NPCs in the Trade Zone, and rewards are predetermined by the trading system.
Conclusion: Is the Axe Shark Update Worth Your Time?
After spending countless hours testing every aspect of Update 34, I can confidently say this is one of Build a Zoo’s most significant updates yet. The Axe Shark Egg provides endgame players with meaningful progression, Seraphine offers a guaranteed path to an incredible pet, and the quality-of-life improvements benefit everyone.
For New Players: This update sets clear long-term goals. Unlock trading early and start building Trade Points while you progress through conveyor tiers. The journey to Ethereal Conveyor and Seraphine will keep you engaged for weeks.
For Veterans: You finally have new content to chase! The Axe Shark Egg variants provide collection goals, maxing Big Pets to level 110 offers progression, and completing your Album through the source tracker gives you something to work toward.
The Bottom Line: Update 34 respects both your time and dedication. Seraphine’s guaranteed acquisition through Trade Points means RNG doesn’t gate you completely, while mutated Axe Shark Eggs provide aspirational goals for the truly dedicated.
Whether you’re just starting your zoo empire or you’re a seasoned tycoon with trillions in the bank, the Axe Shark Update brings something valuable to your Build a Zoo experience. The combination of new content, quality-of-life improvements, and long-term progression systems shows the developers understand what makes this game engaging.
Now get out there and start building toward that Ethereal Conveyor! Those Axe Shark Eggs won’t hatch themselves, and Seraphine is waiting for dedicated traders willing to put in the work. See you in the Trade Zone!
