British dog man

The  is a being from Soos' nightmares, brought to life by Bill Cipher during "Dreamscaperers," in Stan's mindscape.

History
When Bill Cipher establishes a Stan's head shaped arena for Mabel, Soos, Xyler, and Craz to fight him upon, Soos unwittingly speaks about one of his nightmares, a "British dog man." This slip of the tongue leads Bill to create the dog man, who quickly decides to hit Soos repeatedly in the stomach with his walking cane. However, when Dipper comes along to aid them in the fight against Bill, he destroys the dog man with laser beams from his eyes, instantly destroying him.

Appearance
The dog man is an English Bulldog who wears a brown bowler hat, a brown suit, a light green tie, and a monocle on his right eye. He walks upright, like a human, and carries a walking cane. He speaks with a thick, stereotypical British accent.
