The gang shelter from a storm in a candy factory but it turns out to be abandoned save for the owner, foreman, and some gooey green monsters sabotaging the whole place. The owner turns out to be Cass Elliot, who explains the monsters just won't leave and that they have scared her staff away and now run the machines themselves. The gang try to find a way to get rid of them but the monsters have a much bigger aim then just taking over the candy factory and they will do anything to keep from being driven out before they finish their master plan.
