If you go to the Snow Forts and look toward to top, you'll see a doorway saying Music Maker 3000. It's where there's four tiles, drums, red electric guitar, maracas, and blue electric guitar. When you stand on them the instrument plays, I like to stand on the drums tile and play my snare drum. One thing, THEY ARE ALL HUMONGOUS!!!! The giant drums outstage my snare drum, a little.
