SM64 B Button Challenge
Beating a Super Mario 64 level without the B button and stealing Pannen's money
YouTuber pannenkoek2012 placed a $1000 bounty to complete the level "Mystery of the Monkey Cage" without the B button, which is normally required to grab the monkey. I with a couple others reverse-engineered the monkey's behavior and came up with a complex sequence of glitches that eventually tied together to solve the challenge. You can watch my video to get an explanation for the exploit!
