Doors to Doom

In the middle of the night, Mario sleepwalks right into a mysterious pipe in the Bros.' shop. Naturally, Luigi follows him down, where they end up in Dr. Sporis Von Fungenstein's, the mad Goomba scientists, Doors to Doom machine. He sends the Brothers to the skyscraper of Donkey Kong, where they must make their way up the skyscraper to rescue Princess Toadstool from Donkey Kong. When they do, though, she falls through a platform in the floor. Mario and Luigi can't follow her as the platform closes up. They run through another door on the top of the skyscraper to the jungle of Donkey Kong Jr. They must run up vines and chains to escape from the chasing DK Jr. Up at the top of the jungle, they find Bowser Koopa. But they decide to not free him. They escape through another door at the top, which leads to Sub-Con. They soon end up at Wart's palace. Wart is dressed like a skater, and offers a garage door opener for the bigger of the two's hats. They do trade, and use the garage door opener on a door down the way. There, they find Von Fungenstein, who claims that he was really on the side of good, and was merely testing the Bros.' performance. Then he directs them through the door of their appropriate door. Then there is a celebration for them that lasts for days.
