Jimmy Neutron: Boy Genius The Adventures of Jimmy Neutron: Boy Genius
Brittany Tenelli is a minor character in the movie Jimmy Neutron: Boy Genius and a supporting character in the TV series The Adventures of Jimmy Neutron: Boy Genius. She is a close friend of Cindy Vortex and Libby Folfax and is sometimes seen forming a trio with them.
She is one of the show's most prominent supporting characters, appearing in every episode and having lines in a good portion of them.
Like Butch, she had more prominent roles in the TV series than in the movie.
She is a very close and loyal friend to Cindy and Libby. There's even an episode where Libby teamed up with her for a class assignment.
She is one of the few characters who doesn't antagonize Jimmy in any way and she actually seems to admire him.
Also, she seems to form a trio with them, as in some episodes the three are seen hanging out and talking each other.
She's a comic foil to the otherwise brainy Cindy and Libby.
She may be a ditz, but she is very kind and carefree, and also quite playful.
She may be goofy, but she's also an awesome dancer.
She has a good character design.
The scene where she throws two pies in Jimmy and Sheen's faces in the movie is memorable.
It was interesting to see her as part of Butch's team in The Retroville 9, rivaling Jimmy's team.
As pretty as she may be, she is kind of a klutz.
She is often treated like someone nobody likes towards Cindy and Libby, despite her friendliness.
In "Raise of the Oozy Scab", Brittany is revealed to be illiterate.
Brittany seems to be a parody of Britney Spears due to her name, having blonde hair, her liking to dance and sing, speaks with a valley girl accent and wears midriff-revealing outfits (particularly in her "Baby One More Time" music video).
She made a cameo in Jimmy Timmy Power Hour 2: When Nerds Collide!
Brittany's pigtails change position depending on her mood.
Whenever she's excited, surprised, or frightened, her pigtails shoot up. This is seen in episodes like Love Potion 976/J and Return of the Nanobots.
When she's sad, her pigtails droop down as it is seen in the movie.
