Ken is a low-ranked minion who works with his immediate supervisor, Mike, in the mailroom down in the depths of Gru's secret lair.  And while Mike takes great pride in doing a good job, Ken is really much different.  Easily bored with the mundane humdrum of sorting incoming packages (and placing them into one of four color-coded routing pipes which carry the packages off to other areas of the lair), Ken tries to alleviate some of the boredom by playing hand-held video games and stocking up on snacks.  If there's anything he can do to make the job more entertaining (or to take his mind off of it), he'll try it...even if it leads to trouble!

Ken's workspace is cluttered with packages he's fallen behind in sorting, and all manner of old snacks and junk.  It frustrates Mike, who tries to motivate him and keep him focused, but Mike's just not tough enough as a supervisor for Ken to care very much.
