Blowfish

Little fish is a small, dome-headed fish alien that comes from the Planet Pisciss (Pisciss Volann & Pisciss Premann home planet) It saved Kevin's life when he couldn't breathe. It almost killed Magister Pyke by removing his mask. However, he only did so because he hit Kevin. He also developed a strong bond with Kevin, and was upset to see him go.

His species can live in water and stay on land for a short period of time. He is capable of shifting into a helmet to help other species breathe. Inside, the air apparently cold and smells like fish. Apparently, his species travel in packs, most likely because one fish can't defeat an enemy single-handedly. When he supplies people with oxygen, his pupil seemingly disappears, as does his mouth but his side fins remain visible.
