Blowfish is a small, dome-headed fish alien that lives in Piscciss.
Blowfish saved Kevin's life when he couldn't breathe after his Plumber suit broke. It almost killed Magister Pyke by smashing his helmet when he hit Kevin. Blowfish also developed a strong bond with Kevin, who somewhat returned the favor.
Blowfish was sad when Kevin was leaving and even wanted to go with him, but Kevin convinced it to stay on its home world.
Powers and Abilities
Blowfish can live in water and stay on land. It is capable of changing into a mask to help others breathe. When it supplies other species with oxygen, its pupil seemingly disappears. Inside, the air apparently is cold and has a fishy smell.
