Like many other series of 1966, the third season opens in glorious color. Samantha takes Tabitha for her check up, only to discovers that she (now a little toddler) has her powers! Endora can hardly wait to tell Derweed and watch him ""fall to the floor in a emotional heap."" Meanwhile, a client of McMann & Tate insists on using Tabitha's image to sell transmitions, and famous baby photographer Diego Fenman thinks he's lost his mind as Tabitha creates chaos in the studio. In the final tag, Darrin is still unaware of Tabitha's magical abilities.

Endora presents an idea for a great campaign for the Bobbins Bon Bons account, and Bobbins takes a liking to her. He insists that she promote her idea on a TV show, which she refuses due to a ski date. So Samantha poses as Endora, but the deception is short-lived when the real Endora appears, magically, on live TV. Because of the special effects, Bobbins is sold on the idea.

Tabitha speaks out about violence on TV. She pops on a TV show to reprimand two aggressive puppets. Of course, Darrin happens to be watching the show and tells Sam to get Tabitha off the TV. The sponsors say otherwise and Tabitha becomes a TV star. The Stephens are dead set against this and Sam makes sure that the sponsor, Mr. Silverton, brings his own daughter to the show for back-up. Tabitha isn't quite ready for the home audience yet (until 1977 with her self-titled spin-off show) and Robin, the Silverton's daughter wins her chance to be in the spotlight.
