They are the main antagonists of the episode "The Inconveniencing", where they possess Mabel's body and attempt to kill Wendy and her friends for stumbling upon the abandoned shop, but redeem themselves when Dipper does "The Lamby Lamb Dance" to make them happy again. It turns out they hate teenagers as they were killed when they saw a couple of them putting on an offensive song, which gave them a heart attack. As a result, their ghosts remain restless and forever haunt the abandoned Gas Station store.
