Aside the Big mom disaster the chapter offer one big interesting stuff.
We see number 4 get attacked by Franky, is he the same was we see in Oden Flashback?
In that case Ceaser can´t be the one who make them to giants, Ceaser didn´t even kinda know it much.
So let assume Vegapunk was the one who make these monsters to giants, so Vegapunk already work for these creatures over 20years+
I can see Big mom and Kaido also beeing experimence of Vegapunk, his best works. Because that Kaido control the numbers, Kaido know them since 30-40years, he know that they beeing in PH. At this point Kaido isn´t most like even a Oni, im really hyped up to see Kaido flashback and the mystery around him.
So the Strawhats will now fight off the beast pirates, I think Pageone,Ulti,Black Maria and Who´s Who joinig the party soon too.
