Mutty the mussaurus is a major villain in The Star Pirates. He is second in command of the space pirate crew, next to their captain, Spiny Jim. Mussaurus are normally herbivorous dinosaurs but Mutty had sharpened his teeth into jagged fangs and thus became a carnivore. It is unknown why Mutty wanted to eat meat, but maybe he was lured to the crew by gold. He also wore a hook for a hand with a built-in communicator and peg legs.
