Jeannie is a average teenage girl, babysitter and student who babysits George and Joan's Baby in the Tom and Jerry MGM shorts: Busy Buddies and Tot Watchers. She is voiced by Janet Waldo. She has appeared again on Tom and Jerry Tales in Babysitting Blues. She's been voiced by Grey DeLisle since 2008.
Jeannie's a fair-skinned blonde with hair tied back into a ponytail with a blue bow with her bangs hanging down. She also wears a pink blouse with a burgundy skirt and black slip-on shoes.
Jeannie's also not a very good babysitter, because while the baby's parents are out, she regularly relies on the telephone rather than doing her actual babysitting, and Tom and Jerry are shown to be better babysitters than she is.
When the baby crawls out of his bed in Busy Buddies and Tot Watchers, Tom and Jerry both do their best to bring him back home and put him in bed, but Jeannie claims that the two were bothering the baby, and she'd hurt Tom with a broom.
Despite her sub-standard babysitting skills, Jeannie's very kind and friendly and has many friends in high school. Her least favorite and weakest subject is apparently algebra, but she wants to do well in that particular class. In her final appearance, she eventually called the police so they can arrest Tom and Jerry whom they both claim to be "babynappers," until it was discovered that the baby started crawling out of the house, where she could eventually take the blame or not.
In "Busy Buddies", Joan and George are going out and tell the babysitter, Jeannie, to look after an unnamed baby. However, she is more interested in talking on the telephone. At first, Tom and Jerry take the opportunity to help themselves to some food, Jerry helps himself to some cookies and Tom helps himself to a watermelon and milk, but they soon discover the baby crawling away while Jeannie continues to talk on the phone, unaware.
Jeannie is unaware through all of this (even when the baby crawls over her), and at one point even hits Tom with a book for "bothering the baby" when he returns the baby to the crib. At the end, Joan and George return and ask Jeannie how things went. She explains that she had a little trouble with Tom, but the baby was "no trouble at all".
In "Tot Watchers", Babysitter Jeannie (voiced by Julie Bennett) is instructed to look after the baby while his mother (also voiced by Bennett) goes out. However, Jeannie pays more attention to talking on the telephone apathetically than her actual babysitting. In the midst of Tom and Jerry's usual fighting, they see the baby crawling out of its pram. Any attempt to return the baby to where it came from simply results in the baby escaping from the pram again. During one escape, the baby crawls into Spike's dog house. Tom accidentally grabs Spike instead of the baby, and is promptly attacked, scratched and bit. This time, Tom angrily brings the baby back to Jeannie herself, who hits Tom over the head with a broom, thinking that Tom has taken the baby away from her.
Later on, Jeannie is in panic and crying, telling a police officer that she was babysitting, took her eye off the baby for "one teensy minute" and the baby was gone. Tired Tom and Jerry arrive with the baby. Jeannie grabs the baby while the two try to escape, but the police officer (voiced by Bill Thompson) arrests Tom and Jerry, assuming they were "baby nappers".
In "How Tot Watchers Should Have Ended", When Jeannie hits Tom with a broom on the head and Tom shoots her.
Another scene, Jeannie hits with a broom on the head again and until she sees a grape soda and drinks it, but is poisoned.
Another scene, Tom and Jerry arrive with the baby. Jeannie grabs the baby while the two try to escape, but the police officer arrests Tom and Jerry, assuming they were "baby nappers". Until Wonder Woman, Batgirl and Supergirl shows up to tell the police officer it was Cheetah and Batwoman who kidnapped the baby not Tom and Jerry. When the police officer letting Tom and Jerry go and find Cheetah and Catwoman who are the real baby nappers. Jeannie is confused upon realizing that Cheetah and Catwoman are the real baby nappers. Until Wonder Woman, Batgirl and Supergirl transferred to Super Hero High. Wonder Woman, Batgirl and Supergirl take Jeannie to Amanda Waller, who offers Jeannie to enroll Super Hero High. She became Battle Girl. She apparently had a lot of money and could make me lots of really cool gadgets.
