I’m Velma got so scared on her last investigation she peed herself! She realized she needed to wear a diaper on her next adventure or the gang would find out she pee's herself when she's too scared! Shaggy comes to meet her and he catches a glimpse of her diaper. She begs him not to tell the gang.. and he see's an opportunity to make Velma a deal, to keep her little secret.
