Rodney's Mother

 comes looking for her son at the Stephenses' home.

She saw Darrin's ad about a lost dog and comes to get him. Darrin thinks there must be some mistake, since he now knows the dog is a warlock in disguise.

She enters and finds Rodney hiding behind Samantha. She, Darrin and Samantha exhange pleasantries and Rodney's mother remarks on how Samantha has changed. She tells them that Rodney is lonely and is always looking for a playmate. She says he is really not bad, just mischievous.

To get him to change back, she threatens to give him a flea and tick bath and he quickly changes back. His mother says it is past his bedtime and they both pop home.
