Which may be true, but as far as i can remember, anyone called a Sage (as in, hermit) was an actual Sage (as in, nature energy user) Namikazenaruto9 wrote: Also there are two Sage creatures not three. Only Snakes and Toads, Toads are the true protector and guider of Ninshu... We don't know if Slugs are sages. Orochimaru didn't use Sage Mode and he had to get creative to even make use of Senjutsu. For all we know, Tsunade too is physically incapable of using it. Or maybe healing ninjutsu doesn't work well with Senjutsu.

For that matter, we don't know if these animals are the only sage animals, or if they simply are the most famous.
