Tsubumon

Tsubumon is a Slime Digimon whose name is derived from the onomatopoeia for lumpiness (つぶつぶ), and as such is small and blob-shaped. Although it has the appearance of a seed, it is not a Plant-species Digimon. It cannot fly, but it is able to move over land, water, or anywhere, while hopping and bouncing, and it is said that there is no place where Tsubumon cannot move through. However, because of its small body it is sent flying on days with a strong wind, and as a result of that it is often mistaken for a Plant-species.
