Country level Mario Party?

[WarriorWare]

Waluigi and Daisy's profiles both refer to them fighitng "people capable of creating countries through sheer physical strength." Could someone please explain to me who these "people" are, and in what game such things happened?

Mario and Luigi, Wario and Peach, DK and Yoshi all gathered in speech. Sharing their wishes for all they had seen, saying "Let's make a world built on all of our dreams!" Combining their talents, they sweated and strained, completing that world, Mario Land by name...

plus waluigi/daisy were also capable of defeating bowser.
