Suzie and her exasperating baby-sitter Miss Muggs are back again. This time the lady has a now compulsion -- one which young readers will immediately recognize -- cleanliness: A forthcoming trip to the zoo means a full scrub down for Suzie, the dog, the cat, the entire house. En route, Miss Muggs is highly critical of the window washer, the street cleaner and the garbage man. At the zoo, the tiger is too spotted, the gorilla's fingernails are black, the lion's mane is messy. But Miss Muggs receives her comeuppance when the elephant showers her clean with a huge trunkful of water, washing away her entire obsession.
