Jerkell

Jerkells are a kind of criminal from the show, Cerbie's Ashes, where Bosko, the sheriff of the Medium Sized Dipper hates them and attempts to clean the town of them with the help of his trusty gun, Samantha. They were first mentioned by Bosko in episode 2 of the first season of the show, in the scene where we are first introduced to him. Another variety of criminals are the Kariminals, which are very similar to Jerkells.
