Muffin and Lolly both get mini-enemas and are left to battle it out to see who can hold it longer. In reality, it's a trick Step-Daddy uses to make sure they hold the mini-enema as long as possible to ensure complete evacuation. He tells them the loser will not be changed until morning.

They struggle to hold it in, even going so far as to tickle each other in hopes of making the other lose control. Eventually someone loses, however, and the other gets a diaper change.
