Fufumon

Fufumon is a Slime Digimon and a carrier of the X Antibody, and 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 larger 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.

Attacks
 * Chīsana Tetsu no Toge (小さな鉄のトゲ): Spits small iron spikes from its mouth at an approaching opponent.
