I don't know if anyone caught this...but, when was did the Kyuubi come out of Naruto.
It's not Naruto himself because he's standing on the left side and we know it's not a clone because we would of seen him make a seal. Is this some mistake?

It's not Bee either.

If it is a clone, why weren't we informed about it l0l

Edit: It doesn't look like Naruto's Bijuu cloak in which you can see on the bottom panels either.
