Gompers first appears in "Tourist Trapped" standing on Dipper's bed and chewing on Mabel's sweater. Gompers later nibbles on the spine of Journal 3 in the forest. At the end of the episode, the goat picks up a trapped gnome in his mouth and runs off with him.
He next appears in "Headhunters" outside the Mystery Shack several times during the time of the "murder" of a wax sculpture of Stan. Gompers is also mentioned to be the culprit behind the disappearance of the Pines family's tin cans.
Gompers is seen on the roof of the Mystery Shack in "The Inconveniencing."
In "Boss Mabel," Gompers is seen outside of the Mystery Shack when a bus load of tourists arrive. Gompers is also seen in the end credits of the same episode where Stan is being lazy and dancing at the same time, where the goat attempts to steal Stan's fez, which they have a tug-o-war over.
Gompers is also seen twice in "Carpet Diem," once outside at night, and once in the attic eating leftover pizza.
In "Land Before Swine," Gompers is seen eating grass and looking at Stan drive by, giving a tour of the Mystery Shack grounds.
In "Gideon Rises," Gompers is seen chewing on the fallen "S" of the Mystery Shack's sign.
In "Scary-oke," Gonpers appearsvon the Mystery Shack's roof sign.
In "Little Gift Shop of Horrors", Gompers appears in one of Stan's stories, and gets shooed away by Waddles for attempting to eat the pillow on his seat.
When Dipper and Mabel travel ten years before the current day in "Blendin's Game", a young Gompers is seen outside the Mystery Shack.
In "The Love God," it is revealed that Gompers and Waddles have gotten married, thanks to Mabel's matchmaking abilities. As both Gompers and Waddles have been referred to canonically as male, this would make them Gravity Falls' first same-sex couple.
In "Not What He Seems," during the first anomaly occurrence, Gompers is seen rising from the ground because of the change in gravity.
