Petitmon

Petitmon (プチモン)
A Slime Digimon that possesses large horns and tiny wings. As its body is extremely light, it lives constantly floating through the air, and maintains its posture in the air by blowing air from its wings and mouth. Although it usually has a cheerful personality, if the three scales on its belly are touched, it goes into an extremely bad mood. When bodily harm draws near, it spits its "Atsui Toiki" to surprise the opponent, while simultaneously using it as propulsive force to quickly flee, so it's not easy to catch.

Etymology
