Rump




 * Rump - The Dino Squad's mischievous pet dog. He can transform himself into a strange animal that looks like a hybrid between a pig and a horse. The Dino Squad as of yet has not determined the species of dinosaur his "dino form" is supposed to be (although since Ms. Moynihan never "taught" him how to control his transformations as she did the kids, it's likely his dino form is mostly canine and it bears a resemblance to Andrewsarchus). Rump usually gives Caruso a hard time from when he took his jacket in "The Beginning" as a stray dog, up until the episode "Runaway Ugly" when he ate Caruso's cupcake.
