After being sucked into a drain pipe, Mario and Luigi defend the Mushroom Kingdom from King Koopa.

Koopa escapes to the Wild West with the princess.

Princess ends up as the wench of an evil sultan; Marianne and Luigeena come to visit.

The Mario Brothers and Toad try to save Princess from Koopa's riverboat; when their plan goes horribly wrong, Toad gets caught and the Mario Brothers barely escape with their lives.

Mario and Co head to the Linguini Empire to attend a benefit spaghetti dinner; when they arrive, Princess and Toad are separated from the Marios and meet Koopa, who's taken over.
