Pannenkoek2012: "The random bit flip hypothesis shown in this video is just the current leading hypothesis. Before that, it was the ceiling seams, and before that the bob-omb/explosion/coin, and before that landing on the platform/wall at the same frame. Frankly, a gamma ray happening to flip a particular bit seems a bit far-fetched to me. It's completely possible that some in-game mechanic treats the height float like an integer and decrements it, thus decreasing that bit from a 1 to a 0, in which case the glitch would be reproducible, and the bounty would be awarded to the person who submits that. The bounty is not rewarded for hypotheses as to what caused the upwarp, otherwise the bob-omb or ceiling hypotheses would have "solved" it long ago."<br>

A bruteforcer was proven to work to find a glitch where the racing penguin slid off the slide. They tried the same program for the TTC upwarp, but it wouldn't reproduce the glitch.<br>

"This situation is similar to that surrounding the TTC upwarp glitch in that we had footage of the glitch being done, but not a TAS recreation of it. But in this case, we actually were able to reproduce the glitch just from footage of it, whereas the TTC upwarp glitch still hasn't been reproduced. For the record, we've also tried brute forcing the TTC upwarp, but that didn't end up reproducing the glitch." - Pannen, description from [https://www.youtube.com/watch?v=kpnBKNZ2YUs CCM Racing Penguin Falling Off the Slide]<ref>[https://github.com/danebou/Fuzzy64 "Fuzzy64" on GitHub by danebou] (Bruteforcer source code)</ref><ref>[https://clips.twitch.tv/AlertStrangeMetalRiPepperonis "Penguin dies" clipped by RussEfarmer] (original video)</ref>
