I have this one in the video below does anyone know who/where this was made???

ALSO: there's another song too that has what sounds like a Super Mario minigame sounding instrumental with cory saying these adlibs: "Yuhh, Yuhh, Yuhh, (SOMTHING), Yuhh" the something i don't know what he said but it sounded like "Mmhhm" and it was a little intermission between different clips (a few seconds). I believe it was in a very old video of his from early 2015.

what is this?
