When the 4th Hokage sealed the the Nine Tails Demon, a baby that looked somewhat like the 4th but with the Nine Tails chakra was created.
After the 3rd Hokage sealed the 1st, 2nd, and Orocimaru's arms using the same seal as the 4th used on the Fox, why was no baby left over?
It would grow into a very interesting character, given the lineage.
