Sei looked down at himself in horror. His shorts had been replaced with a huge disposable diaper, emblazened with the face of Sonic the Hedgehog. His shirt was riding up a little high and a his bellybutton poked out from between his diaper and shirt. His shoes and socks also seems to have disappeared. Looking back up he started to giggle. It was Jonathan's turn to be confused.
"What are you laughing at you little twerp?"
"If I'm too big for a Sonic diaper then you're way too old for a Bart Simpson's diaper."
His ten year old laugh was high pitched. Jonathan shifted, and his diaper crinkled. His eyes bugged out at the sound and he looked down. His shirt had also changed to a simpson shirt that matched his diaper much as Sei's did.
"What the hell did you do to me?" Sei screamed as he dodged Jonathan's grasp. He ran back up the stairs. Jonathan followed, his thick diaper throwing off his balance. Sei was having less trouble as he tottled up the stairs.
