Plot Synopsis
The Story from the Back Cover:

"Koopa Kid Kidnapped! Luigi to the Rescue? Wendy O. Koopa has disappeared and an embarrassed King Bowser asks the Super Mario Bros. to find her. Experienced princess-rescuer Luigi reluctantly agrees. But all is not as it seems. Can Luigi trust Bowser and his creepy creatures-or does the treacherous turtle have a secret scheme up his shell? As in all Nintendo Adventure Books, you control the action. Only you can make the choices that allow Luigi to beat Boo Diddly, Hot Foot, and the rest of the Koopa creatures. Help him crack codes, solve puzzles, conquer mazes, and subdue enemies. You and Luigi must outwit the Koopas at their own games-or go down in final defeat!"
