Dinosaurus Rex is an orange and aquamarine tyrannosaurus rex in stuffed animal likeness, who comes to life through a child's imagination. Dinosaurus Rex often quotes things as "Isn't that cute? BUT IT'S WRONG!"—this is said to be a reference to Mr. Hollywood from 2 Stupid Dogs. Despite being a carnivorous type dinosaur, Dinosaurus Rex likes many different foods such as fruits and vegetables, but his main favorite is a peanut butter and jelly sandwich with a glass of milk. He also loves marching bands and parades.
