Corn costume guy

The Corn Costume Guy is the owner of a roadside attraction Corn Maze located somewhere in Oregon.

Before the twins' visit
Corn Costume Guy is one of Stan's tourist trap competitors who prank the Mystery Shack every year. Last year, they duct taped Soos to the ceiling, leaving him there for 78 hours.

Season 2
He is seen carrying a box corn as Dipper is specking with a girl, while Grunkle Stan is dropping a swarm of locusts on his maze for payback.

When Stan, the Twins, Candy and Granda return to Gravity Falls, only to see that the Shack was all mass up by the rival tourist trap competitors and he broke one of the RV head with a bat before running off with Granny Sweetkin and the Upsidown town man.
