Pupumon

Pupumon is a Slime Digimon and a carrier of the X Antibody. It has grown a body as light as a bubble, as well as very thin wings and somewhat largish eyes which are very sensitive to movement. If something moves, Pupumon will notice it and immediately spring away, but this doesn't mean it's a coward, as, if the object continues to be unkind and approaches, Pupumon will counterattack.
