I'm betting Mario, Peach, and Toad head to DK Island to ask them for help in the war against Bowser. Cranky, who's some type of Mesoamerican king now, will only agree to help if Mario can defeat their strongest warrior.
Seth Rogen.
Or maybe in this version, the land that DK and Cranky lives in is a neighboring border and kingdom of the Mushroom Kingdom?
