Magaly Lohnes, (or Miss Lohnes), was a teacher at Holy Cross Daycare (until she was wilmotted)
When she first appears in the movie, 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 Spiros, for the seventh week in a row that he had brought Ultra Lord. Sometimes, she makes random parrot noises, hence her name. Once, in "I Dream of Jimmy", she laid eggs of smaller versions of herself in Carl's dream.
Throughout the series, Miss Lohnes 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 tax evasion is worse than rape". She holds plagiarism in the lowest regard.
She plays a minor role in the movie, 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 the worm, calling it Mr. Wiggles, and is riding towards the cafeteria.
In a special sneak peek for the series that aired during the 2002 KCA, it is revealed that she has been running into many trouble during the time she was shrunk such as becoming the ruler of an ant colony.
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, at least over her 80's, since in the eighty-second father's day folly in Make Room for Daddy-O, she states that she remembers the first as if it were yesterday, along with working at a rodeo before she became a teaher for seventy-four years.
She is based on the Mater Dei High School faculty member Mrs. Larsen. 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.
