This is currently my most popular picture on DA.
The idea came to me when one of the groups on DA - Naruto Madness - had a contest for a Naruto crossover. I wasn't part of that group at the time so I couldn't compete in the contest (plus it was done way past the deadline).
Originally Shippou was supposed to jump on Naruto hugging him, but after I thought about it for a while, I came to the conclusion that Shippou wouldn't be too overjoyed knowing that Naruto might be his "relative" (you know demon fox kind of relation). So this is the final version. I hope you like it.
