Keroleen is a kind girl, and good at cheering up kids who have just lost a fight.
Her hobby is collecting clothes, and she can leapfrog into a new costume before you can say ‘ribbit’. Her polka dot one piece is her favorite piece of clothing. She is currently taking special cooking classes, and she can make delicious hotcakes using the secret Donut Pond essence, that Keroppi’s Mama told her about.

Curious Kyorosuke loves discovering new things.
He has the best eyesight in Donut Pond, and can see for 1 km, so he’s always the first to find out what’s coming.

He hates sports though...

Keroppe was born on the banks of Hyoutan Pond, on the other side of the mountain, and moved to Donut Pond recently. He’s the kind of guy that sits under a leaf on the bank of the pond, and before he knows it has been there for three days! He’s softhearted, which often makes him the butt of jokes. Keroppe is good at making masks and little boats from pond reeds.

Denden loves to vague out.
He loves hanging out with Keroppi and co. and doing very little.
