Deuce

Deuce is Soos' equivalent at the Tent of Telepathy. It also appears they do not like each other. He appears in "The Hand That Rocks the Mabel." He has no spoken lines.

History
Deuce appears briefly when Dipper and Mabel visit the Tent of Telepathy. Noting its similarities to the Mystery Shack, Dipper points at Deuce and says that they even "have their own Soos".

Physical appearance
He wears a light blue cap and has hair on his head, no facial hair, and seems much more organized than Soos. He looks almost exactly like Soos, except for the fact that he has hair.

Trivia
Deuce happens to mean "a thing representing, or represented by, the number two," which happens to be the name of the 2|book owned by his employer 'Lil Gideon.
