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 very far. Though it dislikes fights due to its mild personality, when it's in a pinch it can open its mouth wide, suck in air, and swell its body up to three times its usual size (Puff Balloon), surprising its opponent, then escape by expelling the air from its orifice.

半透明な体を持つ精霊デジモン。綿毛のように体が軽いため、常に空中を漂っている。風に乗って移動を行う習性があり、風の具合が良ければ相当の距離を移動することもあるといわれている。争いごとは好まない温和な性格だが、ピンチになると口を大きく開け、空気を吸い込み、体を約３倍まで膨らます『パフバルーン』で敵をビックリさせ、そのスキに空気を噴出させ逃げ出す。
