well, remember he is not a regular fox. He just a huge ass demon mithological fox, which isn't too slim or has soft motions. If you want something soft but tense look for PURI PURI!!!

And Naruto's strength lies in his Harem no Jutsu, that beats everything. The only thing Naruto needs to improve it is the Sexy Sasuke no Jutsu and that way he can beat Michael Jackson too (cuz he is inmune to Harem no Jutsu).
