I second the Iruka/Kakashi dealing with three Narutos! idea above.

Also the Tsunade ones: the three of them lined up in Tsunade's office, Kyuu-naru restrained if he has to be (oh my god, he would HATE that so much!!)

Ino + Naruko, and the fact that they look alike, kind of.
Do they get along? Ino probably approves of the kitsune-things, and Naruko would be fascinated by Ino's femininity. Or they might become rival kunoichi using poor Shika as the competition ground?

And not so much a prompt, as a question: where do they eat and sleep?
