For those curious, the song is "Caramelldansen," by the Swedish band Caramell. The original non-remixed version is here. It's just a fun, nonconsequential dance anthem in the style of "The Locomotion."
I love how Ganon's all, "Screw you guys, I got my own beat!"
And Mister Game & Watch is just kinda freakin' out there.
Oh, and nice hips, Luigi. ;P
