Marilyn has insomnia and in a attempt to cure it, Grandpa accidentally gives her a Sleeping Beauty potion instead. Now Marilyn can’t wake up unless she has been kissed by a prince. Lily and Herman advertise for a prince in classified section the newspaper, but this only attracts a couple of out-of-work actors. Meanwhile, Grandpa is negotiating with an oil company for the rights to use his magic pill that turns water into gasoline.

Herman purchases ten acres in Happy Holiday Valley through a magazine ad. It turns out to be a patch of wasteland in a broken-down ghost town, so the Munsters absolutely adore it. This makes things difficult for the fly-by-night salespeople who get a better offer for the property and want to buy it back.
