Pafumon

Pafumon (パフモン)
A Spirit Digimon that possesses a translucent body. Since its body is light as down, it is constantly drifting through the air. It has the habit of moving upon the winds, and it is said that if the wind's condition is suitable it will migrate a considerable distance. Although it dislikes fights and has a gentle personality, when it gets in a pinch it surprises the opponent by opening its mouth wide, sucking in air, and swelling its body up to three times its usual size (Puff Balloon), then seizes the opportunity to expel the air and escape.

Etymology
Pafu: A transliteration of 9パフ), meaning puff.
