Mudman

Mudmen (マッドマン, Maddoman) are sentient humanoid creatures made of solid mud in Magical Vacation. Chocolat is one of them.

In Magical Vacation
Mudmen have no blood or organs; instead, their heart is a jewel that possesses great power. It is unclear as to what Plane Mudmen first came from, but Moiroroto Village in the Plane of Death is populated by many. This is an ideal environment for the Mudmen that live there, as their bodily composition is entirely abiotic.

The residents of Moiroroto Village have a very esoteric view on life, constantly questioning the very world they live in. The vast amount of knowledge they hold greatly juxtaposes that of Chocolat, whose thought process is much slower.
