Birth January 31 1989 age 30 In the first episode of season 7, "Rusty and Tammi Sitting in a Tree, B-A-S-T-A-R-D", she does mature somewhat as she puts the baby first ahead of their own and asks Rusty to get a job to provide for their son. She gives birth to "Macho-man Randy Cuyler" and breaks up with Rusty due to his lack of a plan for his future. While Granny and Early were shown to be supportive of Rusty's care for the baby. Once alone, both strictly believe the baby isn't Rusty's as he hasn't inherited any squid traits.
She and Randy would appear in "The Inkubator Lives!", now putting all her efforts into providing for the child. She appears to have a job in as a waitress in a Hooter's resturant under the employment of Dan Halen. She wants Rusty to pay for child support so she can feed the baby. Once again though, Rusty gets lost in his imagination and is seen pretending to be a cape crusader, instead of looking for work. When she finds out he stole some money from a cashier, she tells him she won't let him see the baby if he continues like that.
Tammi and Randy appear once again in Season 9's "Ink Is Thicker Than Blood, Which Is Thicker Than Water", where Rusty begins to question whether he really is Randy's father. Unwilling to pay child support for a son that isn't his, he kidnaps Randy and drives off with him, only to discover he is in fact Randy's father after discovering tentacles under his diaper.
- Tammi may also be the only one in her family that works. Her mother never works and it appears her father mostly sleeps on the bed, meaning he probably just takes government checks.
