Long Summary
From the Tamatebako explosion, the Whole Cake Chateau collapses, sending Big Mom, Galette, Morgans and Stussy falling towards the ground. Galette is saved by Katakuri, Morgans falls to the ground and Stussy gets away using Geppo. Carrying Luffy, Sanji gets away and enters safety in Bege's castle. Caesar carries them all away and Germa 66 also retreats, but their castle in Germa Kingdom is attacked by the Big Mom Pirates.

Meanwhile, Streusen uses his Devil Fruit ability to cut the Whole Cake Chateau and turn it into sponge cake. Big Mom is saved by Zeus just before the Chateau crashes into the ground, flooding the island with cream. Big Mom complains that Streusen's ability produces food that does not taste good.

Mont-d'Or falls to the ground but ends up unharmed. Enraged that the Straw Hats had escaped, he orders all the Tartes in Totto Land to pursue them.

Bege takes the Straw Hats to a safe location. Disappointed, Vito confirms that the Big Mom Pirates have all survived the Chateau collapse. Bege also gives Caesar his heart back and frees him. Bege finally ends his alliance with the Straw Hats before leaving. The Straw Hats plan to escape using the Shark Submerge.

Back at the wrecked Chateau, Katakuri divides the army into two units, one to pursue Straw Hat and one to pursue Bege. However, to the horror of Smoothie, Big Mom starts a crazed rampage demanding wedding cake. Opera attempts to flee but Smoothie, unhappy that Opera had lied to his family, orders him to stand up to Big Mom.

The other Big Mom Pirates gather and discuss the situation. Katakuri and Brulee decide to personally pursue the Straw Hats. However, they are interrupted by Smoothie, alerting them about Big Mom's hunger rampage. She continues to destroy the town in rage.
