Super Mario Bros Trapped in the Perilous Pit

the long version

Mario and Luigi are repairing the palace's pipes while King Koopa traveled down the corridor intending to kidnap Princess Peach. Mario tries to fight King Koopa off by using his Super Mario form, but is defeated. Luigi saves Mario from King Koopa by using a Fire Flower. Afterwards, the Mario Bros. try to run off the Koopa Troop, but instead fell into a deep pit. King Koopa also threw Peach into the pit and locked the exit. The Mario Bros. have to cooperate to escape the pit. Mario grows larger by eating a Mushroom, allowing the to reach the top of the pit. Luigi uses the remaining fire in his Fire Flower to burn down the locked door. After their escape, the Mario Bros. defeat King Koopa and drive him off. Mario, Luigi, and Peach return to the castle to celebrate their victory.
