Henrietta Biggle is one of the main members of the Goth Kids, a non-conformist group that usually hangs out behind South Park Elementary and smoke cigarettes. Other popular things to do are dance like Goths, hang out at the local diner and drink coffee, or write poems in Henrietta's room. She lives with her parents, Mr. Biggle and Mrs. Biggle, and her brother Bradley, all of whom she reviles, though her mother seems to think this is "just a phase".
She is often smoking and appears to be the most knowledgeable of the Goth subculture, owning a copy of the Necronomicon and knowing much of the book's background, as seen in "Coon vs. Coon and Friends". She is also capable of driving using her parents' car, shown in "The Ungroundable" and plays the keyboard in the Goth Kids' band.
- "You'd like to wait till I was dead, wouldn't you? You'd like to see maggots eat my face." (Raisins)
- "You kids need to all go put your freakin' Banana Republic clothes back on, right now!" (The Ungroundable)
- "The only thing that can destroy an immortal... is another immortal." (Coon vs. Coon & Friends)
- "That's how I feel when my mother abuses me. I just wanna escape, to she can't hurt me anymore." (Goth Kids 3: Dawn of the Posers)
- "I won't come back because I'll be fucking dead. I'll walk out of that camp and I'll walk the streets until I probably get picked up and gangbanged by criminals until I'mm bleeding out my fucking eyes!!" (Goth Kids 3: Dawn of the Posers)
Henrietta is virtually never seen without the other members of the Goth Kids, and his primary allegiance almost always lies with them... but she was willing to join the Emo Kids when the end of their clique seemed inevitable.

A significant quest in the game involves courting the Goth Kids' allegiance and choosing whether to bring them to the Humans or the Elves. The player must find them behind the school, then learn to dress like them and dance like them to win their friendship. They then join the player's chosen race in the Battle at the School.
