Gompers

Gompers the Goat is a goat who lives near the Mystery Shack. The goat usually finds his way inside the Mystery Shack, and, at one point, he managed to eat all of the household's tin cans.

History
Gompers first appears in "Tourist Trapped" standing on Dipper's bed and chewing on Mabel's sweater. Gompers later nibbles on the spine of book 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.

The goat next appears in "Headhunters" outside the Mystery Shack several times during the time of the "murder" of a wax sculpture of Stan. He 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" and watches a wedding ceremony during Pioneer Day in "Irrational Treasure."

In "Boss Mabel," Gompers is seen outside of the Mystery Shack when a bus load of tourists arrive. He 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.

In "Bottomless Pit!," Gompers appears after Dipper, Mabel, Soos, and Stan fall down the bottomless pit, and after they come out.

Gompers is also seen twice in "Carpet Diem," once outside at night, and once in the attic eating leftover pizza.

In "Boyz Crazy," Gompers chews off Ergman Bratsman's license plate, which Soos praises him for; this later gets Bratzman arrested.

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.

Appearance
Gompers has a dull brown coat, a white stomach, and a dark brown spot on its lower back. It has yellow eyes and horizontal irises. Half of one of Gompers horns is missing.

Trivia

 * Gompers is named after English Labor Union leader, Samuel Gompers.
 * Gompers has horizontal irises like real life goats, as opposed to most cartoon goats, who are depicted as having normal irises.
