Secrets EditIf you are playing with the Teddy Head equipped you can do a triple jump over Sally's eye to go over her head and behind her. When you get behind Sally you can go through a world snake to get to a secret level in which you can find the Poop Head.
If you are playing with the Ball backpack equipped you can turn it into a big ball and play catch with sally. After successfully hitting Sally with the ball about 10 times without it hitting the ground it will burst revealing the Ankh.
