Derpy T-Rex is one of the three skins released under the Derpy Dinos offer. It could be purchased as part of an item deal for a limited time in early May 2021.

Derpy T-Rex could be purchased for $12.99 in a deal that included 15000 coins, a Legendary Potion, 1600 DNA and the Derpy Elasmosaurus skin. It was not available for individual purchase and there may be few opportunities to acquire this skin in the future.

Details of this skin can vary depending on location, platform or time.

Note: The Derpy Dinos offer was released again for a limited time in mid October 2021. The item deal with Derpy T-Rex remained exactly the same for this release.
