Poor Jungle Girl. She falls into quicksand. Jungle boy finds her. Jungle Girl starts to sink while Jungle Boy tells her where and how quicksand forms; why people sink in quicksand; what happens to animals in quicksand; how people can watch out for quicksand; and what people should do if they fall into quicksand. But Jungle Girl does not sink forever. There is a happy and surprising ending. And a quicksand experiment. For someone who has not fallen into quicksand, author-artist Tomie de Paola knows a lot about it.
