Short Summary
Shinobu rescues Momonosuke while Sanji battles unsuccessfully against King. Meanwhile, Big Mom tries to take Zeus back, but Franky and Brook appear and run over her face.

Long Summary
Battle ensues in the party hall, and Queen receives several reports from his subordinates. While he and King are distracted, Shinobu silently drops from the ceiling and attempts to rescue Momonosuke. She uses a technique in an attempt to break the chains. Although she damages the chains, she is caught by King, who throws her off the balcony and sends her crashing into a tower. She takes out a parachute to slow her fall.

Momonosuke's chains finally break, and he falls off the balcony. King pursues him, but Sanji, appearing in his raid suit, intervenes. He catches Momonosuke and passes him to Shinobu before battling King. King gets the upper hand, transforming into his pteranodon form, piercing Sanji with his nose and crashing into a building. At this point, Yamato abandons his battle with Ulti to take care of Momonosuke.

Big Mom confronts Luffy. She recalls how the Straw Hats ruined the Big Mom Pirates' wedding. Luffy and his clones destroyed her wedding cake, and Brook destroyed her only portrait of Mother Carmel. In an act of revenge, she takes out Napoleon and unleashes her Ikoku attack, creating a powerful shockwave. Luffy successfully evades, but the Sasaki was tied to is destroyed, freeing him.

Big Mom notices that Zeus is missing, and catches him being carried away by Nami. Big Mom grabs Zeus, but Frank and Brook appear in their motorcycle and run over Big Mom's face, knocking her over. Brook then slices Zeus in half.

Anime Notes

 * The anime adds the following.
 * When attempting to free Momonosuke, Shinobu uses her ability on the chains.
 * After handing Momonosuke over to Shinobu, Sanji has a brief fight and flight chase sequence against King. In the manga King immediately attacked Sanji by divebombing him into a wall.
 * Big Mom's attack destroying the tree that had Sasaki restrained with his chains is seen. In the manga this was only mentioned.
 * The anime extends the following.
 * Shinobu's attempt to free Momonosuke.
 * Nami arguing with Zeus.
 * Franky and Brook singing a tune while heading towards Big Mom.
 * Franky running over Big Mom with the Kurosai FR-U IV.
 * In the manga, Brook was sitting down the entire time on the Kurosai FR-U IV when he had slashed Zeus. In the anime, he was standing up when he and Franky rode in and jumped off to attack Zeus, before landing back on the Kurosai FR-U IV after Big Mom was knocked down
 * In the English dub, Brook exclaims 'Rain Rain Go Away!" as he cuts Zeus in half, both in reference to the nursery rhyme and the latter being a cloud homie.
