Twins Penny and Paulie are thrilled to be in Tokyo-even if they're stuck in a boring hotel while their dad attends "important" meetings. But when they meet a strange, frog-like creature named Shimesu in the hotel pond, their trip turns into a wild adventure.

Shimesu is a yokai, a supernatural being, and he's in big trouble. Banished from Yokai Mountain, he needs their help to get home. Soon Penny and Paulie are diving through his magical water vortex to destinations across Japan and experiencing the country in ways no visitor ever could!
