Batman is tied up in the Gotham museum with a meteorite dangling above, set to fall on top of him. Believing the Dynamic Duo are finished, The Joker continues with his Zodiac crimes: stealing a statue of Justice (Libra) made from rare Carrera marble, a jeweled scorpion (Scorpio), two rare fish (Pisces) from the park and kidnapping Basil Bowman (Sagittarius). He also kidnaps Venus, who has betrayed him to help Batman! When Batman tracks him down a second time, Joker chains the Duo and Venus in a shallow pool with a large, carnivorous clam!
