• Name : keroppi
  • Birthday : July 10

Keroppi lives with his brother, sister, and parents in a big house on the edge of Donut Pond, the largest and bluest pond around. Keroppi's friends share his love of playing games, especially baseball and boomerangs. But most often he is seen with his little snail friend, Den Den, always tagging along and usually a little behind.


Keroppi’s father Keroppa is a doctor at Hasunoue Hospital. An experienced healer, he can help almost anyone back onto the road of recovery.


Keroppi’s mother Keroma is a master chef, and runs her own small restaurant. She can make nearly anything but Keroppi’s favorite item on the menu is the rice ball! It gives him a boost of energy.

Koroppi Hasunoue

Koroppi may not appear to be as lively and bold as his brother Keroppi, but Koroppi is a steady, hardworking achiever. He’s often mistaken for Keroppi, as both look so much alike! Koroppi’s hobby is tinkering with machines. A born singer, Koroppi has the best voice in the family.

Pikki Hasunoue

Pikki is the only girl of the Hasunoue triplets. A real cutie, Pikki keeps the heads turning in Donut Pond. Pikki loves climbing trees and cooking (she can whip up a mean stack of pancakes with a little help from Keroleen). Pikki is great with names. As the number one baby sitter in town, she knows the names of all the kids born in the Pond.

Baby Brother

Kokero is Keroppi’s baby brother.


Kerojee is Keroppi’s grandfather.


Kerobah is Keroppi’s grandmother.


A trustworthy fellow, Noberu’s the deep thinker of the bunch. He wants to follow in the footsteps of his father, a weather forecaster for the government weather bureau. Noberu can already predict hurricanes with uncanny accuracy.


Keroppe just moved into town from Hyoutan (Gourd) Pond, which is on the other side of the mountain from Donut Pond. Famous for his ability to space out, Keroppe has been known to sit under any available leaf and vegetate for three days straight. His good nature makes him the target of many practical jokes.


A natural peace-maker, Keroleen is always there to offer a kind word or wipe up the tears after an argument. Her passion is fashion: an avid collector of new clothes, she’s seldom seen wearing the same outfit twice. Her favorite outfit is a polka-dot dress. A budding chef in training, Keroleen is learning the secrets of Donut Pond cooking from Keroppi’s mother.


Strongman and leader of the mischievous Ganta-Kyorosuke-Keroppi trio. He may be the strongest frog in the pond (he likes to think so), but the truth is, he’s afraid of the dark and heights! Ganta’s specialty is, wouldn’t you know it, transforming himself into a rock.


Teruteru, the little girl rain charm, has the power to predict the weather! And she is usually right on the money with her forecasts. As a side hobby, Teruteru likes to collect ribbons.


A laid-back fellow with a weakness for daydreaming, Den Den the snail is a favorite with Keroppi, despite the big gap in their activity levels.


Kyorosuke is wildly curious, and loves all sorts of new things. Blessed with superior eyesight – he can see things over half a mile away – Kyorosuke is often the first to pick up new information. Underwater swimming is his specialty. Kyorosuke makes up one-third of the mischievous Ganta-Kyorosuke-Keroppi trio.


Keropatnic is Keroppi’s teacher.
