The Rainbow Troops by Andrea Hirata
Several crocodiles make appearances in The Rainbow Troops. They are presented without much fanfare, as they pose just one of the everyday dangers of living poor in an Indonesian swamp. When a crocodile blocks his way, Lintang, the unlikely star of his ten-student, one-room schoolhouse, simply hacks a new route to class. He is well-trained in the art of making do—although just barely. When his bicycle chain snaps, he pawns his father's wedding ring to repair it. His classmates hope the chain will hold, since Lintang's family has nothing else to pawn, and the bike is his only means of transportation.
