Okay. I know this is somewhat random, and probably a very old topic, but it's just been on my mind for such a long time; it's full-powered Kurama's height. Now, we all know that when Naruto was born his father, Minato, sealed HALF of Kurama inside of Naruto; specifically, the Yang-half. And the Yin-half inside himself. And because of that, Kurama's size shrunk compared to his original height. In Kurama's file, it explains that when at his original height, Kurama's eye, or at least it's pupil alone is bigger than a full-grown human being. Using his eye, here're some examples of Kurama's height after he was split with:

Did see how big it was compared to Naruto? While still humongous, it wasn't exactly colossal like its original size. Now, does anyone remember a Dreamworks animated movie called: Sinbad: Legends of the Seven Seas? If so, remember the giant fish that was mistaken for an island, and Sinbad hooked it on to the ship to make it sail faster? Well here're some examples of how BIG the fish's eye is compared to fully grown humans:

Did you see those? Now, I used the giant fish's eye as an example of how I think Kurama's original size is compared to his half-sizes. Unlike when Naruto stood on the side of its cheek and looked at it straight in the eye, its iris and pupil were no bigger than Naruto. However, just like the giant fish, I think in its original size, Kuramas eye would be sooo big, that a person could stand on it. Unlike when Naruto was speaking to him, he wasn't/couldn't stand on the eye. And as for the Ten-Tails, since the Ten-tails is the biggest and most dangerous out of ALL of the tailed beasts, even at it's full power and size, Kurama would STILL be smaller than the Ten-tails. I imagine that the Ten-tails is probably close to the size of an extremely large mountain; probably not as big as Mount Everest, but definitely big enough to be mistaken for mountain. So big, that it could hold Kurama in it's hand like a toy/action figure. Here's an image as an example of how big I think the Ten-tails would be compared to Kurama at it's full power:

So, what do you guys think? Am I close? Any holes you think need to be filled out? Let me know in the comments below.
