^ And they fought team Dosu on the second day, both facts disprove your idea that Naruto fought for 5 days straight. The second stage only lasted 5 days.R u dumb, Naruto's eye's become's red when ever Kyubi's chakra flow's with in Naruto's body(wihtout Naruto's knwledge) and the chakra turn's to be red....
U could easily say that Naruto is useing his own chakra as long as there is no red chakra and red eyes....
If ut think Iam wrong just give me a scan where Naruto used Kyubi's chakra or Kyubi lend his chakra to Naruto without no involvement of "red"......
Sasuke and co fought Orochimaru on the first day of the exam...
