Stupid Mario Bros' U



Stupid Mario Bros' Pii is a shame for the Pii, obviously. It involves Mario, Luigi, Yoshi and Toad as they mark their territory by peeing on everything, which they learn from Barney in the tutorial level. The player must ride a Yoshi and make it swallow water, then pee it out all over the level. If the player loses a Yoshi by getting hit, they can still pee by using Pee Flowers. When 100% of the level is covered, the player moves on to the next level. Nobody ever bought or played this shame, so the only people who know about it are the Mario Bros., Toad, Yoshi, DK, and Barney, but they all refuse to talk about it.

Story
One day, Mario and Luigi decide to have yet another party involving "friendly competition", so they invited Toad, DK, and Yoshi. Unfortunately, DK has lost his eyesight due to an accident, so he arrives with his new guide "dog", Barney. Soon, everybody becomes bored, and Barney decides to show the Mario Bros. a new trick: marking their territory by peeing all over everything. While everyone else is running away in horror at the thought of this idea, Barney snags an opportunity to mate with Yoshi, producing two babies. They quickly grow into adults and convince the others to follow their lead. This kicks off the actual gameplay, which contains no further story elements in it until the final boss: DK, who is angry at Barney for setting a bad example and at the Mario Bros. for following it.

Gameplay
The player starts the level while riding a Yoshi: Mario rides the original while the others ride Yoshi's and Barney's children (apparently, Yoshi is female in this shame). The controls are simple: use the control stick and buttons (all of them) to move and jump into the water, respectively. Once a Yoshi jumps into the water, it gains the ability to pee, which is necessary to complete each level. Once the entire level is covered in pee, the level is complete.

Trivia

 * Apparently, this is the first Stupid Mario Bros' Pii shame where Yoshi is male.
