The series has three main characters: To these are added the child Yuni, who is female, and a bulky male Tuttle (so-written in the English subtitles) to complete a typical five-character adventure team.

For instance, when Wan becomes angry or sneezes, he turns into a tiger, though he still wears his trousers, as does Bud, who becomes a rooster when he is frightened or disgusted.

Mei Mer's legs are replaced by a porpoise's tail; Tuttle becomes a sea turtle, his cumbersome body becoming an armored sphere.

Each has a stereotypical childish desire: Wan is hungry, Bud Mint wants girls, Mei Mer wants wealth.

Their enemies are the human beings V-Darn and V-Sion, whose names involve a pun on the Japanese word for "beautiful", namely bi for v, and the story begins with all heroes captured and taken to the enemy stronghold, and the three statues taken.
