Adventure Time Season 6 Episode 5 Sad Face Episode Title:Sad Face.Episode Description:With N.E.P.T.R. (voiced by Andy Milonakis) and BMO watching, Jake's tail goes to work at a traveling bug circus once every month when Jake is asleep. The tail works as a clown with the stage name Blue Nose; he is berated by the circus's ring leader (voiced by Brett Gelman) and asked to make his performances "less artsy and more fartsy". Blue Nose is displeased with the manner the ring leader treats a captured chipmunk, who is paraded around like a wild beast. Blue Nose makes a deal with the ring leader that stipulates that if he can pull in more money than the chipmunk, it will be set free. Blue Nose then performs a hilarious routine that brings in money, but the ringer leader tries to not honor his agreement; Blue Nose and the chipmunk subsequently escape, and Blue Nose returns to Jake, just as the latter wakes up.
