Bill Mumy also appeared in A Vision of Sugar Plums (1964) as Michael, the orphan boy who spent Christmas with Darrin and Samantha.
Endora purposely bungles Darrin's name again, this time twice: Donald, and Dennis. However, in a conversation with Samantha, she also speaks his correct first name for only the second time in the run of the series.
The mini-Darrin Stephens chases the boys into the park running past the contemporary known "Friend's Fountain." Samantha waits for mini-Darrin sitting on the fountain lip. The splattering fountain can be heard over Samantha calling out, "You going to be long, Darrin?"
The Park Playground was across from the side entrance of Mr "Deed's Mansion" where they had the Town Meeting in "Red Light, Green Light" (March 04, 1965) on the "Columbia Ranch." The same mansion used in Frank Capra's movie "Mr. Deeds Goes to Town" (1936) with Gary Cooper which was torn down in the 1980's for a come-and-went National Lampoon "Vacation" Film.
