@akagami7:
In any bubble like this one(middle panel)

Hm, it looks like that too in ch 614. Though, why would the dojo be separate from the rest of the island? It would make sense for the palace to be, and to get there, the crew had to take a ride up to it, high in the sky and away from the rest of the scenery.

Of course, it could just be above all the other bubbles, but it seems odd that the other bubble outside is completely detached, aside from the corridor.
On another note: And where exactly is Fishman District? I thought it'd be on the sea floor, but by the direction that Noah is going, it seems to be up above the main island (and not the bubble connected to FI).
Oda really seems like he's pushing the pace here. A quick exchange of attacks, and the battle moves onto the ark… the other SHs are left with the remaining NFP, who essentially are fodder, unless the commanders actually put up a good fight. Still lots of things to cover, though...
