BK

BK is a racoon and the controlled player character throughout most of Donut County; except levels 13 and 22. When BK falls into a hole himself, he must answer to his best friend Mira and the residents of Donut County who are now stuck 999 feet below their homes.

BK works for the Donut Shop, and in turn, the Trash King. His job is to deliver "donuts" to any one that orders them. These "donuts" are in reality holes that slowly engulf objects around them, getting bigger as they do so, and in turn getting larger still. The purpose of these holes is to steal trash from everyone who isn't a raccoon, in order for it to be used by the raccoons. He is fully aware of the purpose of the holes, but only begins to feel remorse and doubt his actions when the holes begin to affect him as well; more specifically when his Quadcopter is destroyed and he is swallowed by a hole controlled by Mira.

Personality
From the start of Donut County, BK is consistently stubborn, caring about little else besides Mira, and his soon-to-be very own Quadcopter. His interactions with other characters show him to be narcissistic and oblivious to the feelings of those around him. He constantly tries to explains how all the problems he cause, all revolving around the "donuts" which he delivers, are actually good and solve more problems than they cause. This behavior continues up until the 13th Level, the Donut Shop, in which he is finally on the receiving end of the holes' destruction, and his Quadcopter is destroyed nearly as soon as he gets it. At that point he begins to realize the suffering he's been causing, and feels genuinely remorseful for his actions. From that point forward he helps to fix the holes' destruction, and return everyone to the surface.
