A Slime Digimon which has grown a body as light as a bubble, as well as very thin wings. Its somewhat largish eyes are very sensitive to an object's movement, and if something moves it notices it and immediately springs away, but this does not mean it's a coward, as if it continues to be unkind Pupumon counterattacks. If the opponent approaches, it attacks by disgorging "Doku no Awa" from its mouth.

泡のような軽い体に薄っぺらの羽が生えているスライム型デジモン。少し大きめの目玉は物体の動きにとても敏感で、何かの動きを捉えるとすぐに飛んで逃げてしまうが、臆病なわけではなく、イジワルをし続けると反撃してくる。敵が近づくと『毒のアワ』を口から吐いて攻撃する。
