Bosko's Recoloration

In the show, Cerbie's Ashes, the Character Bosko, the sheriff of the Medium Sized Dipper has gone through quite the color cange. In the first season, Bosko appeared blue, except for one frame in the episode "Ink Them, Dinkum!", where he was incorrectly colored red, while in the season 2 episode "Bosko's Return" and later episodes he was colored green, except a scene in the episode "Cerbie's Soap Tree, where he was miscolored purple. The reason for this is unknown. Not the miscolorations, but the season 2 recoloration. The season 3 end credits dance was edited to fit his new appearance.
