Super Mario 3D World - Crashing the Game (with 1 player)

I found this glitch whilst screwing around in this game in 2016 or 2017, but I never got around to uploading it... until today! By the way, I didn't edit anything. The game actually crashes if you do what I just done in this video. I duplicated the Koopa shell by stunning the Koopa at the same time it entered its shell, which causes the Koopa to be stuck at the flagpole due to its position of re-entry (there are now 2 shells instead of one), picked up the shell, entered it and then hit the Koopa by touching it with the Wii U GamePad, which causes the game to think that I touched the flagpole whilst in a Koopa shell, causing it to jump to invalid lines of code, and this is what causes the crash. I had to power off the Wii U, because I couldn't access the Home menu on the GamePad. Want more content from me?
