After reading all the feedback I got from the "How to Grow a Second Head" animation, I've done another, called "How to Grow Another Head".
No doubt, it still needs some cleaning up. The ending goes too fast, I think. And I would've liked to put some stop/play buttons for the music, but somehow the code wasn't working as it should, and the play button woudln't actually play anything so I gave up on that after about an hour D:
