Most of a Goomy’s body is water. A membrane covers the whole Pokémon to prevent it from shriveling up in dry weather.
Goomy’s horns are excellent sensory organs that cover all five of Goomy’s senses. Goomy picks up on danger from the movement of the air.
Goomy hides away in the shade of trees, where it’s nice and humid. If the slime coating its body dries out, the Pokémon instantly becomes lethargic.
