|“||These guys live in magma. They sink if you step on them. Careful!”|
|— Magmotamus' Cast Description • Kirby's Epic Yarn|
Magmotamus is a large, red blob-like creature with a squiggly mouth. It has yellow spikes and black and white button eyes. It slightly resembles Galbo.
Magmotamus does not attack and serves as a platform to cross lava. It will sink if the player stands on it for too long. Turning into Weight form and pounding the top of its head will daze them and keep them from sinking. However, pounding the same Magmotamus twice will cause it to break into bits of yarn, and Kirby will fall through into the lava below.
Magmotamus' name is a combination of magma and hippopotamus.
