Quick Summary

from @Asura

Chapter title: "Fluffy and Gooey"
(Raw title とろふわ is a Japanese onomatopoeia for delicious-looking foods. It is one of the lyrics Streusen sang several chapters ago.)

Not sure about the title.
The castle is collapsing.
Bege and the others make use of the confusion and disorder that ensues and proceed with their escape plan.
Bege thinks that there is no need for the assassination plan anymore as they think that the Big Mom pirates will all die as the castle collapses.
But Streusen uses his ability and saves the Big Mom pirates from the debris.
Luffy and Bege pray for luck and head each to their own ship.
Some usual thing happen to Big Mom.
Not having eaten the wedding cake she begins to show symptoms of her eating illness(however it was officially translated)
(Basically her illness kicks in and she will probably go nuts)

The roof of the castle begins to crumble, and a large crack starts to develop. The soldiers erupt in confusion. The many citizens of the capital of Sweet City become mixed up in the destruction of the castle. Sanji and Reiju grab the collapsed Luffy. Judge is carried by Niji and Yonji.

Everyone inside Bege's body is astonished by what's happening outside. The people caught on the slope of the roof are sent tumbling down to the ground. BM is among them.

The only ones safe in the air were Ceasar and Bege.
Bege watches the BM pirates fall and declares in a loud voice that the BM Pirates are now completely annihilated.

The escaping city citizens are rained on by tiles.
Morgans loses control of himself in excitement and starts to take pictures.

Stussy escapes using Geppou.
Ichiji visually confirms that Ceasar escapes to the safe perimeter.

Streusen activates his ability and changes the crumbling castle into a gigantic Whole Cake.
The falling debris changes into sponges and cream, saving their lives.
The BM pirates immediately began their pursuit.

The Straw Hat Pirates and Firetank Pirates assemble at the northwest portion of Whole Cake Island.

Ceasar recieves his heart from Bege.

Just as Katakuri organizes a pursuit team, BM's condition changes.

BM: "There's... cake there... with specially picked ingredients.. The best wedding cake... We...dding...Cake...~"

Big Mom erupts in one of her feeding frenzies.
