Breaking off a piece, Batman frees himself, pulls out a Batknife and cuts Robin loose, and they escape with seconds to spare before the great stone drops.

Joker, believing the duo are finished, continues his "Zodiac Crime" spree, snatching a statue of Justice (Libra), worth a fortune in Carrara marble, from outside Police HQ, just as Venus, incognito as a trenchcoat detective, plucks a jeweled scorpion (Scorpio).

Later, not only does Joker snatch two rare palaremus demnese fish (Pisces) that were on exhibit at the Gotham City Park Fountain, but one of his men kidnaps Venus as well, not long after the Dynamic Duo speed off in a hot pursuit.

En route to their hideout at the warehouse, the Joker's henchmen start shooting at the bullet-proof Batmobile as the Dynamic Duo give chase, forcing them to take a detour.

Back at his lair, the Joker catches Batman and Robin in a huge net and quickly takes them to a water-filled tank, where, along with Venus, they are in due course to become the main course for a giant clam.
