Ma and Pa Duskerton

Pa and Ma were two ghosts who died at and haunted teh Dusk 2 Dawn convenience store. Dipper and Wendy had an encounter with them when them and Wendy's friends partied there overnight.

History
Pa and Ma once owned the Dusk 2 Dawn. When they were alive, 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.

Personality
Pa and Ma had a deep resentment of teenagers. They mean and angry at Dipper at first, but their anger diminished when they found out he was technically not a teen.
