In the expansive underwater world of Meamare, a unicorn family lives in a shell clearing nestled in the sea forests. Only those who are very lucky and patient get to encounter the unicorn parents and their little ones. And once you've seen them, you will never forget them. A mermaid has even managed to become friends with them. She visits them regularly, pets them, and even speaks with them. Even the little horn of a unicorn foal already possesses great magical powers.
