Demetan Croaker, The Boy Frog

けろっこデメタン

The story is about Demetan (Jonathan in the English version), 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 (known as Pookie and later Hilary in different English versions), despite the differences in their social standings: Ranatan is the daughter of the leader of Rainbow Pond (English name, Leopold), while Demetan and his parents are tree frogs, which make them automatic outcasts in the community. Together, Demetan and Ranatan enjoy many adventures.
