Madpole

Madpoles are a species of bluish Tadpoles debuting in the Wii U game, Super Mario 3D World. Their name is a combination of "mad" and "tadpole".

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

If Mario was swarmed by a lot of Madpoles the best way to take these pests out was the Cat Suit and the Fire Flower.

Since Madpoles reapper in Pipeline Boom Lagoon, these enemies are the replacement of the Goombas in floaties and Cheep-Cheeps.
