Aren't you using Arlong Park, Tom? You should have found it there. :p
I wish that Oda would do more with the various numbered keys. Actual strategy is good. Meanwhile, this is pretty standard One Piece.
There probably is, we just haven't really seen it yet. So far, only one key has technically been obtained (Fukurou's, as Franky just beat him [for good, this time]), and we're not even sure which this is.
Meanwhile, we have Chopper trying to collect the keys/help the others, but he currently seems to be in quite a predicament as Kumadori now shreds his furry hide. We're going to be seeing some big Chopper development, I feel.
Chopper hit Kumadori TWICE with his strongest attack AND slammed him into a fridge. Chopper struck him again later (with a lesser attack) and did nothing, and Chopper's own Guard Point was nearly broken from Kumadori's assault.
I'm interested in seeing how this situation goes.
I think something I like about all this is that while it does feel like a standard line-up, there's still some stuff we don't know, and it has been jumping around quite a bit, which keeps things interesting. Look at the starting match-ups:
-Franky vs. Fukurou
-Nami vs. Kumadori
-Zoro vs. Kaku
-Sogeking vs. Jyabura
-Sanji vs. Kalifa
Of course, things didn't stay that way for long:
-Nami is saved by Chopper, who eventually takes on Kumadori
-Sanji is "beaten" by Kalifa, so now Nami takes on the girl (still wondering if Sanji will do anything else now)
-Zoro and Sogeking are forced to team-up (I'm wondering how/IF this "Sogesword" deal will work-out XD )
Right after that, Chopper temporarily helps out Franky before they break off into their own fights.
Some of these battles still seem a bit up for grabs. Who will actually be striking the most in the Kaku/Jyabura fight? Will Robin fight in the end?
I have a feeling that we'll continue to jump between the Kaku/Jyabura fight and the other Strawhats, eventually coming back to see how Zoro and Usopp finish things. Personally, I want to see Kaku and Jyabura get handcuffed together (despite their DF abilities, they could still put up a bit of a fight), at least before Zoro and Usopp are set free (if they are during their fight).
EDIT [gathering thoughts...]:
Fukurou just lost his to Franky.
Kaku and Jyabura each have one, but we know that they're not the #2 key (the one to Zoro and Usopp's cuffs).
Kalifa has one.
Kumadori has one.
