Fufumon

Fufumon is a Slime Digimon and a carrier of the X Antibody whose name is derived from the Fu (歩), and as such is the weakest of its line. It has an extremely light body, so it has floated through the air since it was born, but because it floats so slowly it is easy for opponents to target it. When its life is threatened by an assault from a bigger opponent, it will thrust at them with the horn on its head to intimidate them with all its might, but because the horn is very soft, the thrust will not injure the opponent.
