The Yeastmouth is a creature that never lost it's filter mouth after leaving the water. Hence the name, the main diet of a Yeastmouth is yeast, which they safely consume through their filter mouth. The Yeastmouths have a sweet sounding, but not impressive, song. They are excellent dancers, and can also befreind some creatures with a decent charm. It has a weak bite, so it mainly uses the spiky ball on it's head for self-defense.
