Jenny is a girl with red hair and blue eyes. She wears overalls that show her shoulder blades and part of her stomach and back. She wears a yellow skirt that shows her legs and her short blue shorts underneath. She wears a yellow and blue necklace, blue boots, blue arm coverings, blue socks and blue jewel earrings. She has a BakuPod and a Bakugan Launcher.
In Bakugan Idol, Jenny is seen performing on T.V. Then the JJ Dolls ride in a car with their boss to a fan meeting, where Masquerade challenges Jenny and Jewls to a battle. Though it does not show the battle, it's quite obvious that the JJ Dolls lost against him. Jenny and Jewls, like other henchmen, got the Doom Card and Bakugan launcher sent by Masqurade. Jenny and Jewls intended to brawl with Dan and Marucho. Though they lost, she turns against Masqurade and Jenny and Jewels say good things about Dan and Marucho.
They returned to fight against the Ventus/Aquos Bakugan, Taygen, and finally defeated it after they almost gave up. Her Aquos Siege, Jewls' Aquos Centipoid, and Marucho's Aquos Preyas and Aquos Diablo successfully attempted the "Aquos Quadruple Chain Attack", an extremely powerful Aquos attack against Taygen's "Poseidon's Wave" ability, and defeated her.
In Invasion of the Vestals, the JJ Dolls make a cameo on a big screen TV in the city.
In Virtual Insanity, they make another cameo on another big screen TV just before Billy makes his return.
In episode 22, she and Jewls make a cameo on a poster in Bayview city. Stoica (in a human disguise) looks at the poster and says: "It's almost just as ugly as they are!".
- Her hair color (red) is the color of the opposite attribute of the Bakugan she uses. e.g blue is Aquos and red is Pyrus, but her eye color matched her Bakugan attribute,similar to Jewls.
- In the first Bakugan video game, she and Jewls have their voices mixed up.
