As a member of The Mister Rogers Society at Yahoo! has pointed out, the absence of an Eiffel Tower model leaves its mark in this episode. Rogers uses large puzzle pieces shaped like King Friday XIII, Queen Sara and Prince Tuesday going from the model Castle to the office of Dr. Bill Platypus stage left. Dr. Bill's office is in the Eiffel Tower. This should have been the ideal time to use the Eiffel Tower model.
