Mochimon

Mochimon (モチモン)
Possessing elastic skin, it is a soft-bodied Digimon that uses the protuberances on the underside of its body to toddle about. It came to be called "Mochimon" from inflating its body when it gets worked up, causing it to look like mochi. However, as a result of having a great intellect that couldn't even be imagined from its appearance, its origin is conjectured to derive from a computer's dictionary feature. It understands human languages, and it is sometimes seen freely deforming its body like it's trying to return communications. It produces mochi-like elastic bubbles to restrict the opponent's movement.

Etymology
