He attends the Mystery Fair in "The Time Traveler's Pig." Like many other patrons, he is angered by Stan mocking them about not being able to dunk him, and is disappointed when the ball thrown by Dipper does not dunk Stan, and cheers when Lolph manages to finally put him in the water with his laser.
In "Gideon Rises," he is seen amongst the crowd as Gideon Gleeful announced his plans for the former Mystery Shack. Later, he is seen disappointed along with other townsfolk after it was revealed Gideon is a fraud.
The hillbilly is rather unintelligent, as shown by his question about Rock That Looks Like a Face Rock looking like a rock. He seems to be quite friendly, as shown by his wave to the Pines in "Irrational Treasure," though he can be angered when people mock him. He enjoys playing video games. A woman with round glasses sat next to him at the theater and appeared to be attending the play as his date. 
The man looks like a stereotypical hillbilly. He has brown hair worn in a mullet, a rather tall head, crossed eyes with bags under them, a large nose, missing teeth, and sparse facial hair. He is thin and has a light skin tone. He usually wears tattered, blue overalls, and long white socks with brown sandals. For unknown reasons, he is missing most of his right pinky finger.
