An animated series about the adventures of school friends: Ruru, Mimzu, Spike, Pea, Shushi, Neki, and Greenbo. These indefatigable troublemakers live in the amazing underwater country Oceania. Our characters, like ordinary schoolchildren, learn to make friends, find a common language with each other, cope with tough situations, and overcome any difficulties together. They are never bored - they make up games, take part in school competitions, sing, draw, compose poems, invent, and explore the wonderful world around them. They are helped by a school teacher, the kind and caring little mermaid Lana.
