Tammy Larsen is a minor character who blackmailed Tina into becoming a "bad girl" in Bad Tina. When she is introduced to the school, Tina gives her a tour, and later on gets into trouble with the school and her parents from her bad influence.
When Tammy finds Tina's "erotic friend fiction", including Jimmy Jr. and Zeke, she decides to blackmail Tina into doing bad things. Tina gets grounded, and eventually tells Linda what happened. She encourages Tina to go to school and tell the erotic fiction, as Gene and Louise steal the real one back. Tina tells the fiction in front of the school, as she gets laughed at for being a freak. While Tammy is laughing at her, she starts to pass gas at a rapid speed, a problem she had earlier in the episode, and runs off due to the embarrassment. This makes everyone else forget about Tina's embarrassing fiction, while Jimmy Jr. found it slightly interesting.
In Mazel Tina it is revealed that Tammy is Jewish.
In the promotional images for the episode Bad Tina, Tammy has blonde hair but has brown hair in the actual episode. From her next appearance on in Broadcast Wagstaff School News she has blonde hair again.
