If you have 50,000 coins and are past level 10, an item in the shop becomes available called the Time Machine. Purchase it and place it on one of your islands. Tap on it and then tap the Warp button. Move the cursor left and right to make significant changes in the speed of the song. Watch the hilarity ensue as you turn your Furcorn into a rejected part of Alvin and the Chipmunks!
