Understanding Fish Bone: What It Is and Why You Need It?
Fish Bone is a special quest item in Abyss Roblox that serves absolutely no purpose outside of completing specific NPC quests. Unlike regular fish that you can sell for cash or display in your collection, Fish Bone exists purely as a progression requirement for two key NPCs in the Ancient Sands biome: Marcus and Grumpy Hank.
What makes Fish Bone particularly challenging is its acquisition method. You won’t find it floating in the water like treasure chests or catch it directly like regular fish. Instead, Fish Bone is obtained through a special mini-game mechanic that only triggers while fishing in Ancient Sands. This unique acquisition method is why so many players struggle to understand how to get it consistently.
As you progress through Ancient Sands quests, you’ll notice that Marcus and Grumpy Hank will ask for increasingly larger quantities of Fish Bone. This makes it essential to understand the farming mechanics early and develop an efficient strategy for collecting them. The more quests you complete, the more Fish Bones they’ll request, so having a reliable farming method is crucial for smooth progression.
The Complete Fish Bone Acquisition Method
Step 1: Reach Ancient Sands Biome
Before you can even think about getting Fish Bone, you need to unlock the Ancient Sands biome. This is an archaeological site filled with ancient ruins, fossils, and sand-covered landscapes. The area is visually distinct from other biomes with its desert-like appearance and ancient structures.
Prerequisites for Ancient Sands:
- Complete previous biome progression requirements
- Have adequate fishing equipment (recommended: Boat Tube or better)
- Sufficient oxygen supply for extended fishing sessions
- Basic understanding of fishing mechanics
Step 2: Understanding the Treasure Chest Mechanic
The core of Fish Bone acquisition lies in the Treasure Chest mini-game. Here’s exactly how it works:
The 20% Chance System: While fishing in Ancient Sands, there’s approximately a 20% chance that a Treasure Chest icon will appear on your fishing mini-game bar. This happens randomly and cannot be predicted or forced. When I say 20%, I mean roughly once every five fishing attempts on average.
Critical Timing Requirement: This is where most players fail. When the Treasure Chest icon appears, you must fill its internal progress bar before completing the main fishing bar. If you finish the main fishing mini-game without first completing the chest bar, you’ll lose the treasure reward entirely.
Step 3: The Pro Strategy – 75% Method
After extensive testing and consulting with top Abyss players, I’ve identified the most reliable strategy for maximizing Fish Bone acquisition:
The 75% Method Breakdown:
- Start fishing normally and fill your main progress bar to approximately 75%
- When you see the Treasure Chest icon appear, immediately shift your focus to the chest bar
- Fill the chest bar completely until you see the checkmark indicator
- Return to the main bar and finish the fishing mini-game
- Collect your reward (Fish Bone or Cactus Geode)
This method gives you the best balance between control and efficiency. By waiting until 75%, you ensure you have enough buffer time to complete the chest mini-game without rushing the main completion.
Step 4: Reward System – Fish Bone vs Cactus Geode
Here’s another crucial detail that many guides miss: even when you successfully complete the Treasure Chest mini-game, Fish Bone is not guaranteed. In Ancient Sands, the chest reward can be either:
- Fish Bone (what you want for quests)
- Cactus Geode (needed for Virelia’s quest line)
Both items use the same acquisition method, so you’ll need to farm multiple times to get the Fish Bones you need. This is why having an efficient farming strategy is so important.
Best Fish for Fish Bone Farming
Not all fish are created equal when it comes to Fish Bone farming. The key is selecting fish with predictable, smooth mini-game bars that allow you to focus on the chest mechanic without struggling with erratic fish movement.
Top Targets: Cods and Pompanos
Why These Fish Are Best:
- Cods: Smooth, predictable bar movement with minimal jumps
- Pompanos: Stable movement patterns that are easy to control
- Location: Both spawn abundantly near Crazy Jeff’s Shop in Ancient Sands
Fishing Strategy:
- Head to Crazy Jeff’s Shop area in Ancient Sands
- Look for schools of Cods and Pompanos
- Use your Fish Radar (if available) to identify target species
- Focus exclusively on these fish for maximum efficiency
Fish to Avoid
Problematic Fish:
- Blackfin Tuna: Jumpy, unpredictable bar movement
- Scorpionfish: Erratic patterns that make chest management difficult
- Sharks: High difficulty bars that require full attention
These fish have chaotic mini-game patterns that make it nearly impossible to manage both the main bar and chest bar simultaneously. Stick to Cods and Pompanos for consistent results.
Essential Equipment and Tools
Fish Radar – Game Changer Tool
One tool that dramatically improves your Fish Bone farming efficiency is the Fish Radar, available from Richard NPC in the Forgotten Dome. This tool allows you to identify fish species in real-time, ensuring you’re always targeting the right fish for optimal farming.
Fish Radar Benefits:
- Instant fish identification
- Helps locate Cods and Pompanos quickly
- Reduces wasted time on wrong fish species
- Pays for itself in time saved
Recommended Equipment Setup
Minimum Requirements:
- Tube: Boat Tube or better ($5,250+)
- Gun: Crossbow Gun or equivalent ($4,750+)
- Oxygen: Adequate supply for extended sessions
Optimal Setup:
- Tube: Fire Tube or higher for Ancient Sands
- Gun: Wasted Gun or better for difficult fish
- Accessories: Fish Radar, Speed Potions for efficiency
Advanced Farming Strategies
Location Optimization
While Ancient Sands is the only biome where Fish Bone can be obtained, certain areas within the biome are more productive than others:
Prime Farming Spots:
- Crazy Jeff’s Shop Area: Highest concentration of Cods and Pompanos
- Ancient Ruins Sections: Good mix of target fish
- Fossil Grounds: Alternative spot with decent spawn rates
Time Management Strategies
Efficient Session Planning:
- Aim for 30-60 minute focused farming sessions
- Use Speed Potions during peak farming times
- Track your Fish Bone acquisition rate
- Take breaks to maintain focus and accuracy
Batch Processing: Since Marcus and Grumpy Hank will ask for multiple Fish Bones across various quests, it’s smart to farm in batches. Collect 5-10 extra Fish Bones beyond your current needs to avoid interruption during quest progression.
Common Mistakes to Avoid
Critical Errors:
- Ignoring the Chest Bar: The most common mistake – players focus only on the main bar and miss treasure rewards
- Wrong Fish Selection: Targeting difficult fish with erratic movements
- Poor Equipment: Using inadequate tubes/guns for Ancient Sands difficulty
- Impatient Farming: Rushing through attempts without proper technique
- No Backup Supply: Not having extra Fish Bones for future quests
Quest Integration: Marcus and Grumpy Hank
Understanding Quest Requirements
Both Marcus and Grumpy Hank are key NPCs in Ancient Sands who will request Fish Bones for their quest lines. Understanding their quest patterns helps you plan your farming more effectively.
Marcus Quest Pattern:
- Starts with small Fish Bone requirements
- Progressively asks for larger quantities
- Rewards include progression items and currency
Grumpy Hank Quest Pattern:
- Similar progression system to Marcus
- Often requires Fish Bones alongside other items
- Essential for Ancient Sands completion
Pro Tip: Always keep a surplus of Fish Bones (5-10 extra) in your inventory. Nothing is more frustrating than being unable to progress a quest because you’re missing one Fish Bone.

FAQ
How often does the Treasure Chest appear in Ancient Sands?
The Treasure Chest icon appears approximately 20% of the time while fishing in Ancient Sands, which averages to once every five fishing attempts. However, this is based on probability, so you might see it more or less frequently in practice.
Can I get Fish Bone in any biome other than Ancient Sands?
No, Fish Bone is exclusive to the Ancient Sands biome. You cannot obtain it in any other area of Abyss, regardless of your fishing method or equipment.
Do I need to complete the chest mini-game every time for quest progression?
While you don’t need to complete it for every fish, you should always attempt the chest mini-game when it appears. Since Fish Bones are required for multiple quests throughout Ancient Sands progression, collecting them whenever possible saves time later.
What’s the success rate for getting Fish Bone vs Cactus Geode?
Even when you successfully complete the Treasure Chest mini-game, there’s no guaranteed split between Fish Bone and Cactus Geode. Both items use the same drop table, so you’ll need to farm multiple times to get the specific Fish Bones you need.
Can I buy Fish Bone from other players or NPCs?
No, Fish Bones cannot be purchased, sold, or traded. They are quest-only items that must be obtained personally through the Treasure Chest fishing mechanic in Ancient Sands.
Is there a specific time of day that increases Fish Bone drop rates?
No, Fish Bone drop rates are consistent regardless of in-game time or real-world timing. The 20% Treasure Chest appearance rate remains constant at all times.
Do better fishing tubes or guns increase Fish Bone drop chances?
While better equipment helps you catch fish more easily and complete the chest mini-game more reliably, they do not directly increase the 20% spawn rate of Treasure Chests or the chance of receiving Fish Bone over Cactus Geode.
Conclusion
Mastering Fish Bone acquisition in Abyss is all about understanding the Treasure Chest mechanic and using the right strategy. By focusing on Cods and Pompanos near Crazy Jeff’s Shop, using the 75% method, and maintaining proper equipment, you’ll be able to farm Fish Bones efficiently and keep your Ancient Sands quest progression moving smoothly.
Remember that patience is key – even with perfect technique, the 20% chest spawn rate and random reward system means farming will take time. But with the strategies in this guide, you’ll maximize your efficiency and minimize frustration.
