Farmer Palmer is the antagonist in the Haunting Hour episode Pumpkinhead and Pumpkinhead: Part 2.
Farmer Palmer is a territorial farmer who lives on the isolated Route 12.
On October 31, 2010 three kids trespassed and wandered around his pumpkin patch. Farmer Palmer warned them to leave before he had to do something drastic, but they wouldn't listen. Fed up, Farmer Palmer took the three kids who refused to leave, beheaded them and replaced their heads with pumpkins and turned their heads into pumpkins, making them his pumpkin headed monsters.
A year later history repeated itself when a group of siblings Allie, Scott, and Dave trespassed on his farm on the same day. After Farmer Palmer told them to leave, they took some of his pumpkins leading to the pumpkin heads to follow them and kidnap Scott who threw them in the trash. Both Allie and Scott were his new unfortunate victims.
In the episode's sequel, 'Return of the Pumpkinheads,' we learn that Farmer Palmer died some time after the events of the earlier episode, but his Pumpkin Heads remain on the farm.
It is unknown if he also kidnapped Dave or not.
