My little life on the island

The boy is left in the care of his older teenage brother, who has no time to play with a small child, considering himself an adult. Naturally, they quarrel. The boy, upset with his brother, goes to live on an island. But here’s a surprise: the island turns out to be floating and takes the boy on an incredible journey into a world of animals, birds, and fish. The brother must bring the boy home, but he is terrified of water.
