Iggy Koopa appeared in Mario and Luigi Superstar Saga where he helped guard Bowser's Castle, which Bowletta had hijacked. He is the first Koopaling to be fought. When Mario and Luigi entered his room, Iggy Koopa started spinning over and over again. Eventually, the Bros. became dissy. Iggy then jumped all the way to the middle of the room. Soon later, the battle begun.
