In the primitive world, a giant black woolly beast named Bobo lives with primitive grandparents. It’s a furry, curious, somewhat frightening, but very charming creature. Bobo explores the reality around him, guided by his boundless energy. Each episode is based on a classic plot from one of the folk tales; using these as examples, the series' main character, Bobo, explains basic moral and ethical principles to young viewers and learns to find common ground with various creatures and animals.
