In Super Smash Bros Brawl, Red Shifter made a bunch of stupid challenge levels and called the whole set the RIFT CHALLENGES: I WANNA BE THE MARIO set of levels, warning everyone that the challenges are canon. The design process and play-testing of these levels were mostly broadcasted through Zachnorn's Stickam. Red Shifter has two "extra" challenge levels (9 and 10) that he has not shared with anyone, mostly because he's lazy and because he hasn't finished them in one sitting himself.
