けろっこデメタン

A poor young frog living in Rainbow Pond with his mother and father (a toymaker), who becomes friends with a popular and sweet girl frog named Ranatan, despite the differences in their social standings: Ranatan is the daughter of the leader of Rainbow Pond, while Demetan and his parents are tree frogs, which make them automatic outcasts in the community. Together, Demetan and Ranatan enjoy many adventures.
