Casval despises Pull ups. Anytime his parents put on on him, he instantly wets or messes it just so he can get out of it. His sister keeps rubbing her pull ups in his face, saying shes more mature than he is because he still wears diapers. Casval was pissed off by this remark and planned some revenge. While his sister was away, he snuck into her room, took a pack of her pull ups, and went back to his room. He took off his diaper and slid one of her pull ups on. After looking at himself in the mirror, his silly switch was activated. He began dancing around the room, shaking his lightly padded bum around and saying “Look at me! I'm a big girl now” in a taunting voice. He then ended this little sketch by wetting the pull ups. He then hid the pull ups in his sister's room, which he later showed to his parents and his sister got put back in diapers. Little scamp.
