One of ALF's cousins. He eats light bulbs.
ALF thinks he has found Blinky when he reads in The National Inquisitor that a couple in Barstow claims to have a space alien living with them that eats cats, frozen yogurt, and light bulbs (Episode: "Alone Again, Naturally").
Willie takes ALF to Barstow, but it turned out to be a hoax by Betty Susla. Returning home, ALF sees a car pass by with a Melmacian in the back seat. ALF excitedly tells Willie there is another of his species on the road, but Willie says they are along a back road in the country and there has not been a car seen for miles. It is likely ALF only imagined Blinky out of a strong desire to reunite with his family.
