Gompers

Gompers the Goat is a goat who lives in the Gravity Falls Forest right next to the Mystery Shack. The goat usually finds his way inside the Mystery Shack, and at one point, ate all of the household's tin cans.

History
Gompers first appears in "Tourist Trapped," standing on Dipper Pines's bed and nibbling on Mabel Pines's sweater. Gompers later nibbles on the pages of book 3 at the forest. At the end of the episode, the goat picks up a trapped gnome in its mouth and runs off with him.

The goat appears next in "Headhunters," appearing a couple of times outside the Mystery Shack during the time of the murder of a wax sculpture of Grunkle Stan. It is also mentioned to be the culprit of who ate all 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, appearing to take Stan's fez, which they have a tug of war over.

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

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 Bratzman's license plate, which later gets Bratzman arrested.

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.
