after that i said how can i be the eight tails i have only been in the sound village but i didt learn any jutsu's there because i was there intil after a monster got sealed inside of me. they told me that the monster was the eight tails fox and that's why im the eight tails. i said now that i think of it there was eight tails. so you can teach to controll it like you can controll the nine tails. naruto said sure i will. go ahead and communicate with it by going in your soul. you'll see a cage.
so when i was in my soul i saw a cage and something talked to me at first i was scared then i knew that it was the eight tails. when i came out of my soul i had one tail. and a second tail grew. then a therd tail grew.then a fourth tail came. then a fifth tail came. then i got unstable. then they stoped me.
