She appears in "Dude, We're Getting the Band Back Together", "Brain Drain" and in the "Mix and Mingle Machine" ("Cheer Up Candace"). She was first addressed by name as Lacie at Vanessa's costume party ("Druselsteinoween").
In "Dude, We're Getting the Band Back Together", we learn that Lacie has been friends with Vanessa for at least six years when, while showing Perry his preparations for Vanessa's 16th birthday party, Doofenshmirtz produces a picture of Vanessa's 10th birthday wherein Lacie is seen.
Along with the rest of Vanessa's group of friends, Lacie is allergic to bees as shown in the episode "Skiddley Whiffers".
She attended Vanessa's party in "Night of the Living Pharmacists" and is seen in Vanessa's class in "Doof 101"
Lacie is a slightly framed teenage girl with purple hair, probably dyed, which she wears in pigtails. She wears a black shirt that has red and white striped sleeves, a red dress, black knee high platform boots, grey earrings, and a black brace around her neck. She has big blue eyes and dark red lipstick. Her head shape is also similar to Stacy, her non-punk counterpart. She is likely very short as in spite of wearing platform boots she is often the shortest person in a given scene.
- It has been said at the San Diego Comic Con in 2009 that she is the equivalent of Stacy for Vanessa.
- Often identified by P&F fans as a "Goth", in Brain Drain it is revealed that she and the rest of Vanessa's friends are punks.
- Lacie appears to really enjoy dancing since it's when her most cheerful expressions occur.
