Jackovasaurus
A smelly yellow blob that can't talk to people and was the last of its kind found in a place where people eat squirrel brains. It's also what the people who make South Park used to laugh at Jar-Jar Binks from Star Wars.
My cousin's a Jackovasaurus. He tried to talk to me and it was like watching a cat try to play chess.
That kid in class is a Jackovasaurus. He eats cereal for dinner and thinks it's a luxury.
My dog's a Jackovasaurus. He barks at ghosts and still can't find his way home.
