Ice-o-pede

Ice-o-pede appears in "What is Life?," where Ice King is seen riding it and commands the Ice-o-pede to attack Finn. However, it attacks Ice King instead. It is defeated when Neptr hits it with pies filled with boysenberries and poison, causing it to crash into a wall where it dies, as he and Finn escape on the Balloons.
