Leaping Lizards is the second title in the Nintendo Adventure Books series.
 Plot Synopsis
The Story from the Back Cover:
The Mushroom Kingdom is Hopping Mad
When His Royal Highness is turned into a rabbit by the devious Morton Koopa Jr., only one plumber can save him. Luigi leaps into action to save the King from a life of hopelessly hopping-and almost becomes a Koopa casualty himself!
As in all Nintendo Adventure Books, you control the action. Only you can make the choices that allow Luigi to beat Morton and the rest of the Koopa Kids. Help him crack codes, solve puzzles, conquer mazes, and subdue enemies. You and Luigi must outwit the Koopas at their own game-or go down in final defeat!
Either Larry Koopa or Ludwig von Koopa are also competing in the International Mushroom Games with their siblings.
