Boo!

A timid boy doesn't want to play with the other children at a birthday party. Eager to prove to his mother that he's not really shy, he hunts round the garden for a goose. Instead, he finds a monster and creeps up behind it, shouting, 'BOO!"—but it's not a real monster, it's just a clockwork toy. Next he sees a tiger. But the tiger isn't scared of him either—it's really a cat. Gradually the boy builds up enough confidence to jump out at the other children, and as a reward for trying so hard to join in, his mother has a special treat—a toy goose which the boy calls BOO!
