Synopsis:
An old 1950s NHK radio drama featuring the three titular monkey brothers, this anime updates the story for the '90s audience of the original broadcasters' new satellite channel. The brothers try some crow soup, start a fire on the mountain, and race the king of the Pig People--like kids do.
