NOTE: Only head and Magic Ball, the rest is in Iggy's model.Larry's second appearance is in the last world of Super Mario World, the Valley of Bowser. In battle, he uses Iggy's attack pattern and defeating condition. He sits on top of a tilting platform on top of lava and is immune to all of Mario's attacks. However, unlike Iggy, Larry's platform has three Lava Bubbles that jumps up and down. He can also throw more than one fireball at one time. Larry needs to be jumped on until he falls off his platform. After the battle, Mario kicks away his castle and gains access to the Front Door. This is Larry's first time being the last Koopaling to fight so far. Like the other Koopalings, his in-game design does not match official artwork.
