Mosomoso is a blue, fuzzy creature with wide shiny eyes, rosy cheeks, and a body largely covered with curly fur. It does not appear to have limbs or any other facial features. While floating, Mosomoso has a fluffier appearance, with its rosy cheeks being invisible and its eyes being shut. When it attacks, its fur forms sharp spikes similar to a hedgehog's.
Mosomoso appears in the later stages of Dedede Resort, namely Stages 8, 9, 10, and 11. It floats gently down from the sky and moves around the ground upon landing. When threatened, it juts out spikes that can damage the Kirbys. Despite this, Mosomoso can be defeated quickly with as little as one Kirby. Mosomoso is more vulnerable while floating in the air, as the Kirbys do not need to pummel it at all, instead being able to slam it onto the ground to defeat it.
- There are sprites of larger, turquoise-colored Mosomosos in the game's data, but these are not present in-game.
