It's Lizzy's roommate's birthday, so she encourages her to blow out her birthday candles while making a special wish. The next morning, Lizzy wakes up and is livid at her roommate! Overnight their reality shifted, now everyone thinks their diapered, mindless, little ones. Her roommate admits she wished that it was a simpler time in life, and that apparently meant they were back in the playpen. Lizzy begins to regress, talking with a lisp, wetting her diaper and finally squatting down to make a messy diaper.
