ALF (ALF #4)

ALF does a personality switch with Kate in "It's All in Your Minds." Then ALF tells the family about the time that he had to deal with a monster while he was part of the Melmac orbit guard in "Monster Mash." And in "One Herd to Go," ALF is stuck at home alone while the Tanners go out for the evening and ends up getting snatched by a coat burglar.
