It’s not just an inspiring story, it’s also the perfect ending that the Wii U deserved.Here is what it says in the offial page:
101% Clear
Originally, it was believed that a level called Trimming the Herbs would be the final uncleared level. However, after over seven years, the creator of Trimming the Herbs revealed that the level was, in fact, a convoluted sort of troll. Despite a general belief both then and now that tool-assisted speedruns (TASes) were not possible on the Wii U, the creator had access to a hardware-based TAS prototype which was used to develop and clear-check TTH. It was apparently intended to be revealed to the public as such, but the level remained relatively obscure even in the community it was designed to troll and was eventually forgotten (until Team 0% uncovered it). Since the level was not uploaded legitimately, it was excluded from Team 0%’s list of uncleared levels. As a result of this shocking revelation, Team 0% considers Super Mario Maker 1 to have been 100% cleared on 15 de marzo de 2024, the day that Yamada (aka “kazeihinn”) cleared The Last Dance.
However, this isn’t quite the end of the story. Trimming the Herbs isn’t impossible for a human, and on 5 de abril de 2024 (only a couple days before the SMM1 servers shut down for good), after over 100 hours of practice and attempts, a player by the name of Sanyx91SMM2 did what the original creator could not: he achieved the first true clear of TTH. Since TTH was excluded from the team’s goal due to the nature of its original upload and 100% was already achieved, we choose to treat this clear of the “secret final boss” of Super Mario Maker as the 101st completion percentage to signify his dedication to going above and beyond in the effort to truly complete every level in the game.
