Again another challenge from Jirokichi Suzuki which Kaitō Kid is about to make another heist at a jewel that can move around. In front of the museum, Sonoko is showing the a trick which was quickly solved by Conan, leaving a mad Sonoko yelling at Ran why brought him here. Jirokichi came and invites them inside the museum. They see that the museum is really crowed, which they also noticed that there is a crowd standing at a aquarium. Jirokichi explains that there is a red diamond upon the turtle called the "Blush Mermaid". Jirokichi then tells them that there is a story behind the turtle, which later Inspector Ginzō Nakamura is getting the peoples who are not involved with it away from the museum. Kogorō also appeared which Ran thought that he wasn't coming, but he said that he changed his mind after watching it on the news. Later, the museum has been heavy guarded by various of SWAT-looking officers, which the crowd goes wild outside. Then Kaitō Kid then starts his heist with another impossible looking magic trick taking both the gem and the turtle, leaving a card behind at the place where the turtle "Poseidon" was.
