There’s going to be a party in this hygiene-centric picture book that teaches little ones how to keep clean. There is not a part of the body that is spared as Manning and Granström (Supermom, p. 262, etc.) take readers down the path to clean-dom. They start by informing them that there are more harmful germs underneath fingernails than on a toilet seat! A Komodo dragon pictured on the same page has claws, they learn, that are so dirty that just one scratch can cause an infection. People brush their teeth to keep down odors from plaque and decay, while small fish get a meal while cleaning the teeth of the larger grouper fish. Free of wordiness and pedantry this has a good dose of gross-out factor and fascinatingly relevant animal facts. Everyone arrives at the party well-scrubbed and proceeds to have loads of fun getting dirty again while eating, playing, and face-painting. The glossary of useful words adds still more information to this already packed and lively lesson. The drawings of an ethnically diverse cast of characters are pudgy and cute, while the animals are realistic with bright watercolors adding splashes of light. This takes all the drudgery out of coming clean! (Picture book. 3-7)
