Wendy Corduroy (voice by Linda Cardellini) is a tall high school girl with a part-time job at the Mystery Shack with a very laid back attitude. Dipper has a huge crush on her, but she has been dating Robbie since The Time Traveler's Pig. Dipper and Mabel enjoy hanging out with Wendy, at least until her rambunctious teenage friends show up.
Wendy is a mellow, down-to-earth, fun-loving and slightly lethargic teen who is a part-time worker at The Mystery Shack. She is just like any other ordinary teen, who wants to be an adult. She has been in numerous relationships with boys such as Ruster Om, Eli Hall, Stoney Davidson, Mike Huerley, Nate Holt, an unnamed guy with tattoos, Danny Felman, and Mark Epstein (who she forgot to break up with) and now as of The Time Traveler's Pig, Robbie.
She sometimes visits the cyberchase fighters and go on adventures with them and hangs out with them.
