Can anybody tell why Madara is collecting the bijus in tail order. And I remember in one episode or somthing it said something about collecting them in order or else everything will fail. May be they need the One tail first to seal the Two tail, coz the two tails power is greater and so on.. so they need the 8 tail before the 9 tail. And I strongly think Madara has something to do with the Kyubi personally. May be its the kyubi he is after but to capture it he needs the other tailed beast captured first!
