Due to being a tree frog, he and his family were outcasts in the community, and he and Ranatan spend the series trying to fight for change in Rainbow Pond.The series was very popular in Japan and is still one of the country's best-loved nostalgic anime.In America, however, the series was turned into two movies, The Brave Frog and The Brave Frog's Greatest Adventure, both produced by Harmony Gold.
