This is the final episode in which Penguin is the main antagonist. Soon after this season, the revamp emerged and Penguin became "reformed", although Batman occasionally questioned him about other crimes of which he had knowledge.
Penguin deduces that the Batwing must carry a cloaking device identical to the Raven's, but somehow doesn't seem to make the connection between Wayne Enterprises and Batman.
This is the second episode to feature Batman with red eyes, the first one being His Silicon Soul (1992), though that one was a duplicant of Batman.
This episode's title would also be used as a riddle in the live action film "Batman Forever."
The music played on the car radio before the Penguin destroys the bridge is also played in Almost Got 'im (1992).
