Made this with the K.K. Rider soundfont that I picked up over at Mario Paint Hangout!
FOR THOSE WHO DON'T UNDERSTAND THIS: K.K. Rider is a dog from the game Animal Crossing who plays various songs on guitar while humming or "singing" along with lyrics. If the song sounds too simplistic and quiet, that's because it's trying to mimic the style from the games themselves. Look up some YT vids sometime.
