The Donald Boxed Set — Edward Gorey

In Donald and the . . ., Donald finds a crawly creature. His mother lets him keep it in a jar, but soon it disappears. Donald takes to bed with painful ribs. But when he's all better, he looks in the jar and discovers a fine 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 surprises him, too.
