What T-Rex does
12x+ earnings boost (community reports up to 15.5x when upgraded) and high-frequency mutation upgrades — the strongest pet currently reported.
T-Rex is classified as a Mutation upgrade pet. You can deploy one pet per farm floor, so the practical question is whether this role beats what you already have equipped rather than whether the pet is good in isolation.
How to get T-Rex
T-Rex hatches from the Dinosaur Egg at a 0.5% chance. The egg costs Robux only from the Egg Merchant. Hatching is pure chance with no pity system, so budget for multiple attempts at low hatch rates.
