Hehe, I was going to suggest a big fluffy black domestic-sort of cat for Kurenai. One of the ones where you reach out and pet it, and it's purring away as it mauls your hand. =P

Asuma-bear! I love it!

I'd like to think of Iruka as a canine of some sort, probably leaning more towards the domestic variety. He's faithful and loyal and good with children, after all.

When I first read this I imagined kinda-disneyfied critters, sort of like The Lion King. Then I realized the fact that, well, paws can't do handseals or throw kunai. Hooves even less so.
(Are all the medic-nin ponies? Shizune and Kabuto (and poor dead Rin!) omg.

Damn it, I want to draw arts for this now. >___>

And I choked on my beer when I read "digivolve". Hilarious!
