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.

Donald encounters a difficulty when a splinter enters the calf of his leg.

In this curious tale, four children, accompanied by their faithful cat, stumble around in the dark and ask, "What's going on when the lights go out?" A lot of imagination and a little bit of science (cue a flashlight and an orange) inspire a creative conclusion. To these young minds, why we have day and night is a big question that can only be answered by one (very hungry) little bug.
