Back in the store, the wish machine's screen is flashing "wish fulfilled".
Meanwhile, you can hear the blonde guy and scott talking as they lay together naked. As you wonder what is to become of you, you can feel yourself regaining flexibility. You're getting bigger. Legs, still made of rubber, sprout on either side of your opening. Arms follow, and both gradually get bigger as you grow. By the time you're four feet you're mostly human, except still made of rubber. You grow back to your old body, and realize your ass hurts.
Scott and the blonge guy haven't noticed you yet.
