A squirrelly ALF decides to make his presence known to the neighborhood by crashing the Tanners' Halloween party. Fortunately, everyone is in costume, so ALF is assumed to be one of the guests, dressed up in an alien outfit. Although ALF is the hit of the evening, Willie (Max Wright) worries that the Melmaccian's presence will spoil his chances for a job promotion. ~ Hal Erickson, Rovi
