This is just a mash up of Pico's and Boyfriend's vocals in Darnell. Albeit with a minor tweak or two as to make it so they don't both sing at the same time the entire time. (And the burb cause why not?)
Also yes, I charted it, it's a little rough around the edges I think.
This uses Psych Engine and a Weekend 1 Port (https://gamebanana.com/mods/512609)
The icons are edited versions of the Mario's Madness icons.
I'm too lazy to do a custom thumbnail, and I honestly don't care to get verified. This was just for fun since I didn't see anyone else do this yet, so, it now exists... And no, I'm not giving you the chart.
