Iggy from Super Mario World 3D print model

The Koopalings return in Super Mario World, aiding Bowser in Dinosaur Land. Iggy is found in #1 Iggy's Castle in Yoshi's Island, where he guards a Yoshi trapped within an egg. During battle, Iggy fights Mario by charging at him on an upside-down, shell-like platform floating back and forth in lava. Iggy cannot be hurt; instead, he gets knocked back by Mario's attacks. Iggy also throws fireballs at Mario. Iggy is defeated by Mario by being knocked into the lava surrounding the upside down shell. If the player defeats Iggy and then jumps into the lava and dies before the screen fades out, the main map music goes silent. After Iggy is defeated, the cutscene afterward has Mario detonating the castle with explosives and causing it to collapse.
