An ocelot who came to love humans, and a boy who became friends with an ocelot.

Oliver the Ocelot loves fish. He tries to catch some, but he isn't any good at it. It doesn't help, either, that another ocelot is mocking him. But when he meets a boy who is fishing with a fishing rod in the same river, he teams up and becomes his best buddy.

Together, they go on a journey and face green monsters and dangerous, rocky canyons. Both Oliver and Mason bring out the best in each other's character as they have fun and are confronted with the dangers of the wild.
