So, I had an idea. In a video made by a channel known as boundry break (i think) on youtube, He discovered that all the underground pipe areas are linked together, so theoretically, if you could go from one to another, maybe using the wall jump glitch, could we achieve a time less than the wr? I don't think a lot could work, but I do think a few could, the third underground area could possibly work but I dont know if, even with the height, it would be possible, as idk if there is a barrier. Do try, I cant really seem to pull it off.

no, requires game genie, could be a fun category though

Thank you. Maybe soon it'd become one? I think a game genie category would be a good.

Can you post a link to the video?

This is not possible, because on the “edge” of the underground section, there is an autoscoll-lock object, making so that you can’t go any farther than the desired amount. This would be cool, but if you use hacks, then you will just get stuck in the pipe. (I have tried it before).
