The Tiger cub is not happy with the cloudy day: the sky is covered with clouds and the sun is not visible. A resilient Monkey calls him for a walk. On the way, they meet friends: the Mole and the Elephant, who go for a walk with them. Then they come to the reservoir, from where the Hippopotamus, the Crocodile and the Turtle come from, and they also go for a walk with them. The Monkey sings songs, and friends start to sing along. The walk lasts a whole day, and even the Tiger cub changes mood.
