My parents used to read this to me when I was really small. I remembered it for twenty years, and even when I asked them about a creature who was mischevious and got a little boy in trouble, they didn't have any idea what I was talking about. I realized I wasn't crazy when I suddenly remembered the title and found the book online.Anyway, the reason I remembered it for so long is that it scared me a little... I started looking out for odd-looking creatures doing misdeeds. It has good morals and a sweet ending. A nice read-to-your-kids book.
