Madpoles are uncommon enemies that calmly swim on the water surface. If they spot Mario, they swim to him, and will keep doing so if Mario dives into the water, trying to ram him. They can be defeated by any attack. Madpoles appear in Rammerhead Reef, The Bowser Express, Deepwater Dungeon, Sprawling Savanna Rabbit Run, and Pipeline Boom Lagoon.
