Brittany Tenelli is a minor character in the franchise.
Brittany is a very pretty girl with greyish-blue eyes with reddish pink eyeshadow and blonde hair that is worn in two long pigtail braids held together by four pink holders on both sides. She wears a white and pink camisole that reveals her midriff and belly button, a pink short-sleeved cardigan, pink sweatpants, and pink Mary Jane shoes with white socks. In Jimmy Neutron: Boy Genius, she wore silver and gold bracelets on each wrist, one of each color on each wrist.
Brittany is a very kind, cute, ditsy, clumsy, bubbly, bouncy, innocent, and perky girl. This makes her a ridiculous foil to the brainy Cindy Vortex and sassy Libby Folfax. She is very happy-go-lucky, and with her head in the clouds, she's often confused in a situation. She is an Italian-American friend of Cindy and Libby, who is also a backup dancer with them. Most of the time, she appears as a background character but occasionally hangs around with Cindy and Libby.
