Shunned by his fellow lions because of his unusual blue colour, Lenny wanders the earth until he comes upon a group of bare, dejected trees. They are sick because it doesn't rain and it doesn't rain because the clouds cannot drink from the sea as they used to. The water is too dirty. Lenny is so sad for his new friends that he cries, and the clouds cry along with him, making rain and giving life to the trees again. Lenny finds a new purpose in his life and sets out to clean up the sea.
