Alomomola is a pink fish-like Pokémon with darker pink markings on its heart-shaped body and fins. It has large dorsal and ventral fins resembling hands, each divided into four sections and tipped with a paler pink. The shape of the Pokémon resembles an ocean sunfish, as it lacks a proper tail fin. Its eyes are round with golden irises and a mark that appears to be an eyelash extending up and back toward the rest of the body. It lives in the open seas. If it finds an injured Pokémon floating at sea, Alomomola will heal the Pokémon's wounds and carry it back to shore. It heals Pokémon using its special membrane enveloping its entire body.
