Seeing Smoothie wring fluids out of that woman's body reminded me of Tsuru's Wash Wash abilities, and to a lesser extent The Juicer from That's so Raven. That's horrifying.
As everyone mentioned, the Enraged army has some interesting abilities. It was great seeing Nami participate in the fight, though I wish we got to see her giant thunderbolt. I winced when Luffy got Haki-sandwiched by those two family members.
Things are getting tougher and tougher for the gang, I wonder how Pedro and Brook will get through the security.
