Gwynne is a dental hygienist who attends the same aerial silk class as Janice in The Muppets episode "Got Silk?" She's quickly befriended by Miss Piggy who's taking the class for the first time and initially mistakes her for an instructor. Piggy bonds with her over the fact that they've both recently been dumped, and tells Gwynne it's fine for them to be besties even though she's a talk show host.
Piggy later invites her to vacation with her in Ibiza, Spain. She offers to fly her first class as Gwynne is assumed to have never been able to afford such a trip before on her salary. Piggy attempts to pair off with Gwynne for the portion of the class that requires a partner, but Gwynne teams with Janice instead.
