Pa and Ma Duskerton were two ghosts who died at and haunted the Dusk 2 Dawn convenience store in the episode "The Inconveniencing". Dipper and Wendy had an encounter with them when Wendy's friends and them partied there overnight.
Ma and Pa once owned the Dusk 2 Dawn store. When they were alive, teenagers were reportedly a scourge on their store, "always upsetting customers with their Boomy boxes and disrespectful short pants!" as Pa said.
Pa and Ma tried to ban teenagers. They then retaliated with their new-age rap music, which was so "shocking and hateful" to Pa and Ma that they were both stricken down with double heart attacks, killing them both. Thus, they hate teenagers and haunt the Dusk 2 Dawn, where Dipper, Mabel, Wendy, and her friends later break into. They use their ghostly powers to give the teens ironic punishments, and speak through a possessed Mabel Pines. They only stop when Dipper reveals that he is not a teen, and allow them to leave in return for Dipper performing the Lamby Lamby Dance.
Pa and Ma are both slightly overweight senior citizens. They both wear glasses and still have their uniforms on from when they were alive. Pa wears an apron with his name tag on it, and Ma wears a shirt with a skirt and a coat with her name tag on it. If they get angry enough, they can catch themselves on fire.
Pa and Ma have a deep hatred of teenagers. They were mean and angry to Dipper at first, but their anger diminished when they found out Dipper was "technically not a teen", which made Ma and Pa act a lot nicer and sweeter.
Powers and abilities
Pa and Ma can physically control objects and people within their store, to the point where they can change a person's form, or bring inanimate objects to life. Pa has shown the ability to light himself on fire, grow in muscular mass, and conjure things up.
Pa and Ma once owned the Dusk 2 Dawn when they were alive. During their lifetime, teenagers were a scourge on their store, always upsetting customers with their boom boxes and "disrespectful" short pants. Pa and Ma banned them, causing the teenagers to retaliate with their rap music. The lyrics to the music were so shocking that they were stricken down with double heart attacks. Thus, they hate teenagers and haunt the Dusk 2 Dawn when Wendy and her friends break in.
