Crissie is a video-game player in Coolsville.
Crissie is a preadolescent Caucasian girl, with long blonde hair tied into a ponytail. She wears a blue T-shirt with pink letters PU on it.
She's a real sore loser and hates Scooby-Doo for always beating her and even resorts to calling him a cheating puppy.
A Pup Named Scooby-Doo
She ran into the gang while searching for clues and expressed her hatred of Blake's Videorama because Scooby-Doo always beat her scores. She tried to get a better high score, but Scooby still trumped her just by using his tail and while sitting in a lounge chair without even looking at the game. She left in anger wishing the arcade was out of business, making her a possible suspect to be Bigwig, but she turned out to be innocent.
