BACKGROUND: Yoob is from the Planet Shroob. Nobody knows whether he was once a Yoshi to begin with or is simply a huge fungus-dinosaur thing. He is the only Shroob that doesn't fight. After the Shroobs make him grow with their guns, he eats Mario, Luigi, Baby Bowser, the other Babies and the Cobalt Star Shards! He gets his energy from turning the Yoshis into monstrous Yoobs and seems to enjoy the thought of renaming Yoshi's Island Yoob's Island.
