Mudman

Mudmen are humanoid creatures made of solid mud in Magical Vacation. They were born when the land was nothing more than soil, implying they have existed for millions of years. A known mudman settlement is May Village in the Abyssal Realm.

Physiology
Mudmen have round egg-shaped bodies with thick arms, stumpy legs, and three circular holes for faces. A Kovomakan snakeweed grows over top of them, and their bodies contain magic jewel "hearts". Some mudmen possess vast esoteric knowledge of the universe.

In Japanese, mudmen often end sentences with んだなっす ~ndanassu, as opposed to です desu or ます masu.
