Join Peter Pea as he journeys alongside a spoonful of vegetables through a person's digestive tract. Cutely illustrated as a spectacled, bow-tied dork, Peter dons galoshes to trudge through saliva and a hard hat to observe mastication. After that, it's a game of chase the bolus! A cutaway of the human body periodically lets us know where we are, and declaratory text supplies the (sometimes unpleasant) facts: "Stomach juices turn food into a chunky slush." No amount of Peter surfing various green liquids ("Cowabunga!") negates the ick factor, which means that certain kids will enjoy the heck out of this entry in the First Graphics: Body Systems series. Any story that ends with a pea dressed like Indiana Jones outrunning a boulder of feces is okay in our book.
