Winifred Fowl, (mainly called Miss Fowl), is a teacher at Lindbergh Elementary. When she first appears in, she has a standard teacher role. When Jimmy questions the standard of research on the school projects, Miss Fowl hastily shifts the focus to show and tell instead of answering. She also shows annoyance at Sheen, for the seventh week in a row that he had brought Ultra Lord. Sometimes, she makes random parrot noises which is most likely why her name is Miss Fowl. Once, in "I Dream of Jimmy", she laid eggs of smaller versions of herself in Carl's dream.
Throughout the series, Miss Fowl usually only appears to fill the part of the part of a teacher. Most often, she has just concluded a lesson on some random topic, such as "why cowboys are bow-legged." She plays a minor role in Jimmy Neutron: Boy Genius, where she gets shrunk by Jimmy's shrink ray, though Jimmy was not aware of it. She is first threatened by a worm, giant by her standards, which had been living in her apple. Although none of the children realizes it, she is passed over by the Yolkians and becomes the only adult left. At the end of the movie, she has tamed worm, calling it Mr. Wiggles, and is riding towards the cafeteria. She has an important role in Substitute Creature, where Jimmy accidentally mutates her into a fifty-foot tall spinach monster. When Jimmy brings Thomas Edison to the present, he becomes infatuated with her, to the point that he does not want to return to the past and the time stream is in danger. Her age is unknown, yet she appears to be in her late years
She is based on the Mater Dei High School faculty member Mrs. Larsen. The creator of The Adventures of Jimmy Neutron: Boy Genius, John A. Davis, attended Mater Dei High School had Mrs. Larsen as an Economics teacher.
In the video game Jimmy Neutron: Jet Fusion, the Virtual World Reproduction Machine transforms her into The Goddess of Fire and being the second boss of the game, the boss of World 3. In order to hurt her, the player has to blow a wind turbine with the primary fire of the Gust Buster Fan to open a pit of acid in the ground, then going up to her and using the secondary fire of the GBF to knock her into the acid. Doing this 2 more times rewards the player with the second idol.
