The Blueberry cops are policemen that first appear in the episode "Candy Streets" where they stop Finn and Jake from climbing aboard the train Pete Sassafras is in for not having any tickets. They are preparing to arrest them, but Finn and Jake convince them to check if they are good. In response, one of the cops licks Jake. Realizing that they are trying to solve a case, Finn and Jake are released.
Although they are both very similar in height, size, and color, there are differences between the two blueberry cops. For instance, both of them have a different nuance of color, one of them being light blue and the other being dark blue. The light-colored one also has a mustache. They both wear blue police caps.
- Unlike the Banana Guards, the blueberry cops seem to be quite competent.
