Otamamon

A larva Digimon whose skin has not yet fully hardened because it chose to live underwater. It swims in lakes and rivers upstream of the Net Ocean with its large tail, and occasionally climbs up onto rocks with its developed forelimbs and does vocal training. Its mostly undeveloped hindlimbs act as rudders in place of its tail, which has gained propulsive power, contrary to typical organisms. It is valuable among Child levels in that it signals its upcoming evolution clearly, but since its potential for mutation is extremely high, caution is necessary in its training. Its Special Move is sending the opponent into an eternal slumber (Lullaby Bubble).

水中生活を選択したため、まだ表皮の固まりきらない幼生デジモン。大きな尾でネットの海上流の沼や川を泳ぎ、時には発達した前肢で岩によじのぼって発声練習をしている。ほとんど未発達の後肢は、推進力得ている尾の代りに、舵の役目をしており、普通の生物とは逆になっている。成長期の中では明らかな進化を予感させる貴重な存在だが、突然変異の可能性も極めて高いため、育成には注意が必要。必殺技は相手を永遠の眠りに誘う『ララバイバブル』。
