Expected Returns
Using conservative estimates:
- T-Rex: Can generate 100M+ Sheckles per hour with proper setup

- Avoid using T-Rex during low-value crop periods
Post-Event Predictions
Based on previous limited events:

FAQs
How rare is the T-Rex compared to other prehistoric pets?
The T-Rex has the lowest drop rate as the only Divine-tier prehistoric pet, estimated at 1-2% from eggs. Legendary pets (all others) have approximately 15-20% rates each.
Can I get prehistoric pets after July 11, 2026?
No, the Pet Mutator and all prehistoric content will be removed after the event ends. These pets will only be obtainable through trading with other players.
What’s the best pet to sacrifice in the Pet Mutator?
Start with common pets from Basic Eggs (2,500 Sheckles). Higher rarity pets give more eggs but aren’t always worth the trade-off. I recommend using duplicate rare pets for the best value.
Do prehistoric pets work with the new Amber mutation?
Yes! The Raptor specifically has a 2.26% chance to apply Amber mutations. Other pets can spread existing Amber mutations through their abilities.
Which prehistoric pet is best for beginners?
The Raptor offers immediate benefits with movement speed and doesn’t require complex strategies. Brontosaurus is also beginner-friendly with its straightforward growth boost.
Can multiple T-Rexes stack their abilities?
Yes, multiple T-Rexes can work simultaneously, but they won’t copy mutations from each other’s affected fruits. Each operates independently on its 20-minute timer.
Will prehistoric pets need special food?
No, they eat the same pet food as regular pets. However, they consume food 25% faster due to their size, so stock up!
Is it worth spending Robux on prehistoric content?
If you’re serious about Grow A Garden, yes. The exclusive nature and powerful abilities make these pets invaluable long-term investments.
Conclusion
The Prehistoric Update has delivered six phenomenal pets that each bring unique value to your garden. Whether you’re chasing the divine T-Rex or content with a speedy Raptor, remember that this limited-time event won’t last forever.
Start sacrificing those spare pets, complete those hourly quests, and make the most of this Jurassic opportunity! These prehistoric companions aren’t just pets – they’re your ticket to gardening greatness.
