There's the Talky Tina bobblehead from the episode "Living Doll" (starring Telly Savalas, pre-Kojak fame). The bobblehead talks, saying her memorable line "My name is Talky Tina and I'm going to kill you!" The price for this item is $17.99, due to the talking feature.
The second in the series is the spacetastic Invader Bobblehead from the episode "The Invaders", starring Agnes Moorhead(Endora from "Bewitched"). It retails for $12.99.
And finally, from one of my favorite episodes, "Nick of Time" (starring William Shatner), there's the Mystic Seer bobblehead. Fashioned to look like the dinerrific tabletop fortune teller, this bobblehead comes with fortune-telling cards. It is also $12.99
