Jennifer is a tall, teenage Caucasian female, with long blond hair.
During these events, she wears a white blouse, a blue mini-skirt and a blue headband.
She is a heavy user of "Valley Girl" slang.
Jennifer was on hand to meet Daphne, Shaggy, Scooby-Doo and Scrappy-Doo when they arrived at Hillside High School to investigate the appearance of the creature. Daphne told Jennifer that the creature was big news.
Jennifer was pleased that her "famous reporter cousin" had arrived to help find the creature that had been scaring the student body and disrupting school activities. Jennifer then showed Daphne a picture of the creature in the school newspaper.
At that point, Toby Wallace arrived with some bad news. Due to the creature's rampage, the school dance had been cancelled. Jennifer thought that was a "bummer". Jennifer clearly had a crush on Toby; when he referred to her as "babe", Jennifer was so smitten that she fainted.
Jennifer reappeared later, once Toby had been unmasked as the creature. That put an end to her crush on him.
At the end of the episode, Jennifer was dancing in the gym with Scooby.
