Corrected entry: When Commodore Schmidlapp (Penguin in disguise) walks around exclaiming "Extraordinary", about seeing the Batcave, he seems to have forgotten about being there before. It happened along with the Joker in "The Penguin Declines" (S2 EP39).

Correction: The movie takes place between the first and second seasons, so he hasn't been there yet.
