Try as he might, the impossibly small arms of Tyrannosaurus Rex mean that it can’t take its own profile picture, zip up a sleeping bag, or even hold hands with a She-Rex.

It’s an equally trying time for Toy Story’s plastic dinosaur Rex who wants to shed his party pooper image. In Disney Pixar’s latest animated short, Rex finds himself in a position where he can use his arms to get a (bath time) party started. It’s disco lights and dance tunes, an epic bubble bash like no other, and it’s all thanks to the king of the hot tub Partysaurus Rex.
