This episode, filmed in Chicago, shows famous landmark Marina City, under construction in 1962. The corn cob shaped structures are still an iconic landmark in photos and movies made in Chicago.
Released out of order as Tod and Buz are already staying in the hotel but in the next episode Lizard's Leg and Owlet's Wing (1962), they are just arriving at the hotel. Of course, Lizard's Leg and Owlet's Wing (1962) was the Halloween episode and needed to be shown the week of Halloween.
