Cool find! This probably won't be relevant in any runs, but other slopes like this might be "clippable" too. I'll try to replicate this clip on my WiiU to see if there's a discrepancy between versions.

I came up with this username during the early 2010's when I was young and the word "epic" was thrown around like crazy. B is my first initial, and 13 is my lucky number. It's simple and lame, but it makes me remember simpler times. (Kinda wanna find a new name though lol)
