At the bottom of the C building. Luffy barely manages to hold onto a small ladge and begins to climb out, carrying an unconscious Momonosuke up the chute.

At the Biscuit Room, Zoro and Tashigi battle Monet, with Monet almost breaking Tashigi's shoulder with her snow powers, but Zoro comes in and vertically splits Monet in half with a powerful Ittoryu technique. Monet recovers shortly after and attempts to attack Zoro but is defeated by Tashigi.

Anime Notes

 * While Zoro was talking about Kuina to Tashigi during the Loguetown flashback, they were not clashing their swords like in the manga.
 * When Monet is cut, her left side falls to the left and her right side falls to the right, having been cut vertically. However there is a moment in which Monet's right side is falling to the left. In addition to this, when Monet is on the ground, her legs are together even after Zoro's sword has cut her completely in half.
 * Zoro is standing in front of Monet after cutting her in half instead of behind her like in the manga.
 * The anime adds the following scenes:
 * Monet asking how Smoker is and Tashigi telling her that he will not be beaten.
 * While fleeing from the gas, Usopp ends up in a room filled with animals contained in jars.
 * Brook and Kin'emon finding another group of kidnapped children.
 * Luffy climbing out of the garbage dump.
 * Tashigi collapsing after Monet's defeat.
 * There is an animation mistake: After Zoro cut Monet in half, Tashigi stand up in her feet and in her left hip, appeared her sword but before that moment, she lost her weapon.
 * When Monet is biting Tashigi's shoulder, her bottom teeth are squared instead of being spiky like the upper ones.
