Rex, the Tyrannosaurus Rex from the Toy Story films, is a misunderstood dinosaur. Although he is in the form of a terrifying tyrannosaurus rex, the toy is hilariously skiddish and has a heart of gold. But after taking a back seat for so long, Rex is finally getting a short of his own. Check out the image preview here below of this short, titled Partysaurus Rex, which will be attached to the Finding Nemo 3D re-release.

Here’s what Partysaurus Rex director Mark Walsh (animator for previous Pixar films like Finding Nemo, The Incredibles, and Ratatouille) told Entertainment Weekly:

A trailer for the upcoming 3D re-release of the hit Disney*Pixar movie, Finding Nemo, has been released online via Yahoo! Movies.

The movie follows a clown fish named Marlin (Albert Brooks) who loses his son Nemo (Alexander Gould) and must search the ocean and overcome its many obstacles in his desperate attempt to find his only child. With only a fish with short-term memory loss named Dory (Ellen DeGeneres) to help him, the duo will encounter rehabbing sharks, a passing whale, easy-going sea turtles, hungry seagulls, irritable crabs, and a slew of others on their quest to find a little fish with a bum fin who could be anywhere.
