Darlene

Darlene is a character who appears in the Gravity Falls episode "Roadside Attraction". She is an employee at Mystery Mountain, a tourist trap in Oregon that boasts actual attractions, unlike Stan Pines' Mystery Shack. While Darlene appears human at first, she is actually a shape-shifting spider-like creature known as an Arachnimorph.

History
In "Roadside Attraction," Stan tries to give Dipper an example of how confidence can get a girl by using his flirting techniques on Darlene. Darlene flirts back at Stan and the two go up Mystery Mountain together. When they reach a cave, Darlene shows her true nature to Stan and traps him in her web. Stan calls for help via walkie-talkie and after Darlene sees this, she reveals her true full form to him.

When Stan escapes thanks to Dipper, Mabel, Candy and Grenda, Darlene chases after them. When Candy pulls the release lever on the Trambience they are escaping in, it sets off a chain of events, eventually trapping Darlene under the giant boot of the tourist trap's statue. Darlene tries to flirt with Stan once more to trick him into releasing her, which Stan almost falls for, but he is stopped by the kids. Darlene is left stuck under the giant boot.

Appearance
When in disguise as a human female, Darlene has tan skin with tan marks over her eyes in the shape of her sunglasses and on her shoulders where straps were present. She has sandy-blonde hair and a brown birth mark on her left shoulder. She wears black pants, a black belt with a circular light pink buckle, a hot pink tube top and shoes, a pair of red butterfly sunglasses, a pink bracelet on each of her wrists and dreamcatcher earrings. She also wears bright pink lipstick and aqua eye shadow.

In her true form, Darlene is a horrific arachnid creature. She has a tauric body structure, with the lower body of a spider and a vaguely humanoid torso for an upper body. Her body is covered in grey and black hair and she has four green eyes on her head. While her upper body has arms, they do not have hands and end in curved feelers which she likely uses for weaving webs.
