He's a dinosaur. And he's very very small.
He's green, and he likes to eat green things.
He moves very quickly, so be careful, because you might lose him.
He has the ability to morph into other animals, such as a lion or an elephant. If he becomes an elephant, he's pink and eats peanut butter and jelly sandwiches.
His name? Butt. Or But. I have yet to get clarification if that's with one "t" or two. I have a hunch it's with two.
