1 Key

1 Key is an any% category which involves skipping the first Bowser fight in (Bowser in the Dark World). The central glitch was discovered in mid-2015, and public ally revealed when sonicpacker uploaded a video showcasing it. The strat involves using PU movement to navigate in front of the door, exploiting the facts that PUs have no water, and that the door-opening action takes precedence over entering the water within the course of a frame. The first ever TAS of 1 Key was released on September 29th, 2016, a year after the skip's discovery, with a time of 4’21”67. The current record stands at 4’21”17, although no video has been released of the full run.
