Summer Days with Coo
Kouichi Uehara is a fourth grader living in a quiet Tokyo suburb. One day, he finds a large stone that turns out to be a fossil-a baby "Kappa" named Coo, who had been buried underground for 300 years. Kouichi and Coo quickly become friends, and Coo moves in with Kouichi's family. But adjusting to human life isn't easy for Coo, who longs to find others of his own kind.
