Doors to Doom

Doors to Doom is the sixth book in the Nintendo Adventure Books series. It was written by Bill McCay. It is the first book in the series to give the player straight points instead of having them collect coins to determine their score, and it is also prone to breaking the fourth wall.

Plot synopsis
The story from the back cover: "Knock, Knock, Trouble's There When Mario and Luigi open the strange door that suddenly appears in their Brooklyn plumbing shop, they plunge into the weird world of Dr. Sporis von Fungenstein, the mad Goomba scientist. He bounces our fearless heroes on a journey through a dangerous jungle, Subcon, and the Mushroom Worlds. Mario and Luigi must survive the attack of wicked Shy Guys, Ninjis, Wart, and the incorrigible Kong Family. As in all Nintendo Adventure Books, you control the action. Only you can make the choices that allow Mario and Luigi to overcome the obstacles they face at each mysterious doorway. Help Mario and Luigi crack codes, solve puzzles, conquer mazes, and subdue enemies. You and the Mario Bros. must outwit von Fungenstein at his own game&mdash;or go down in final defeat!"
