This is the second episode that was not aired in Japan. The first was "Chinpokomon".
The McCormicks have a robot guard even though they are poor. It could have been bought with Kenny's life insurance premium, the half-million they got from Cartman as compensation for Kenny dying (in "Cartmanland") or for just something that happened to be there for some reason.

In "Clubhouses", Stan builds a treehouse on his house's backyard. This treehouse is seen again in "Spookyfish". But, this episode shows Stan's backyard empty. The same error was made in "Quintuplets 2000", but they may have just taken the treehouse down after "Spookyfish".
