Kappa no Kaikata - S01

A young man passes a pet shop on his way home and, seeing a kappa in the window, decides to buy it on a whim. He brings the creature home and names him Kaatan. He has never owned a kappa before, so he relies heavily on a book he bought about raising and training kappa. The book offers several good tips for bringing up a smart and well behaved kappa, and it all seems very simple. Unfortunately, putting these techniques into practice and actually making them work is not quite as easy as the book implies. Kaatan seems to understand things at first, but usually ends up either forgetting what he has learned or is not interested in learning in the first place. However, this particular young man has a lot of patience, and he continues his possibly fruitless effort to raise Kaatan into a pet he can be proud of.
