Meet Donald, a little boy who has little adventures that to him are very big indeed. In Donald and the . . ., Donald finds a worm. His mother lets him keep it in a jar, but soon the worm disappears. Donald takes to bed with painful ribs. He forgets about his new pet while he recuperates, building a matchstick castle and imagining things. But when he's all better, he finds in the jar something that takes him by surprise. In Donald Has a Difficulty, when Donald hurts his leg, his mother (as wise as she is kind) knows just what to do. And Donald learns what hurts and what doesn't - and that takes him by surprise, too.
