Well that's news to me. If you were taking bets on who would win a fight between an octopus and a shark, I'd probably say a shark without a second thought. Killer Bee's line made me curious enough to look it up though, so here's an example of an octopus taking out a shark. I don't know what's more impressive though, Bee's ability to tame his 8-tailed beast and be in complete control while using his version of the jinchuuriki cloak, or Kisame's infinite chakra-battery Samehada that he can surprisingly fuse with. However, I can say that Naruto (as a series) is looking less like a battle between ninjas and more like a battle between freak shows at this rate. Speaking of which, what's with Samehada anyway? It's nice to know that it has a limit on how much chakra it can absorb in one go, but it still looks like a huge porcupine more than anything else. Also, I don't really need to hear Kisame talk about how big it's gotten. -_-;

The other notable part is Fuu's attempt to retrieve Ao's Byakugan by making him cut off his own head off. While Danzo probably wants the eye retrieved so that other villages don't have a Konoha kekkei genkai (bloodline ability), is anyone else starting to think he might want it for himself? Sharingan + Byakugan? Not saying it'll happen (because it's the wrong-sided eye anyway), but that would be pretty overpowered.
