Barney Gumble is the lone character of the Barflies collection, and is often seen in a drunken, confused state. However, when he is sober, he is shown to be a kind and generous man. Despite Barney's Bowlarama now costing 250 donuts after the Christmas Event, Barney remains as a non-premium character.
