Yak Girl was harder to create.
While both costumes were unique to this episode, Trayce admits Yak Girl was more difficult to create. "Beth’s arms were inside the costume and the rear legs rolled. The costume was a total balancing act," she notes. "The rear of the costume had to be detachable for a stunt joke. Due to this costume having so many moving parts it was definitely more difficult to construct. Beth had two days to rehearse in the Yak Girl costume."
