Short Summary
Marco uses his phoenix flames to halt the spread of Ice Oni, giving Chopper more freedom to produce the antibodies. Scratchmen Apoo attempts to take back the virus antidote, but is attacked by X Drake in his allosaurus form. With enough allies to protect Chopper, Zoro, Robin, and Brook decide to have Marco fly them up to the dome's roof.

Elsewhere, Sasaki prevents Franky from attacking his subordinates by transforming into a triceratops and charging into him. On the third floor, Black Maria has transformed into a giant prehistoric spider and pursues Sanji as he tries to get away, wanting to make him her pet. On the fourth floor, Jinbe stays to fight the horde of Beasts Pirates there while Luffy goes on ahead, and after Luffy leaves Jinbe confronts Who's Who. Outside the dome, Page One and Ulti resume hunting down Nami and Usopp after defeating Hihimaru.

Meanwhile, Yamato and Momonosuke have hidden out in a storeroom, where a big dragon statue is located. Yamato reveals to Momonosuke that the statue was damaged by Ace when he came here to kill Kaido a few years ago.
