With some misgivings, the Stephen's leave Aunt Clara with Tabitha. The Springers are charmed by Darrin and Samantha. Then Samantha phones and learns Tabitha has brought a toy monkey to life. Samantha pops home and meets Louise Tate. She pops back to Chicago where Springer is phoning Larry. Since Louise had told him Samantha was at home, Larry apologizes that Darrin's wife couldn't go to Chicago.
