Frog is sad. The real problem is that he doesn't know why. Rat tries to cheer him up, but only succeeds in making him cry. And then, Frog starts to laugh . . . until everyone is laughing. Frog is happy again and Little Bear, for one, is very relieved.
Max Velthuijs has written a typically true-to-life tale of the mysteries of moodiness and the relief that follows its banishment. Once again, for children and adults alike, Frog manages to show that it's all right to feel.
This is the twelfth story about Frog, his feelings and his friends. It combines all the graphic simplicity and emotional integrity of the previous eleven picture books about him.
