The Plumbing Solutions of The Super Mario Brothers is a massive, cultured nation, ruled by Mario with an even hand, and renowned for its vat-grown people, ritual sacrifices, and irreverence towards religion.

The Super Mario Brothers's national animal is the Goomba, which is also the nation's favorite main course, and its national religion is 1-Up Musʜʀooмs.
