Keropyontchi appeared in the 15th Anniversary Character Poll as a male adult candidate.
Keropyontchi resembles a blue frog with small eyes, a wide mouth, and stubby hands and feet. He also very slightly resembles Ginjirotchi. The Game de Hakken!! Tamagotchi 2 artwork depicts him as green with more frog-like limbs and narrow eyes.
Keropyontchi is boisterous with a big voice, and has a tendency to over-react to everything. He's got so much extra energy that he occasionally goes up on land to bully the Mushichi, but he still has a good heart. When he come across females, Keropyontchi can't help going red all over out of embarrassment. Keropyontchi's favorite food is hanpen, which is a type of surimi, a fish puree usually molded into many shapes such as squares, triangles and circles.
