Whoops, I keep forgetting to check this. Well, the bubble blowing guy's actually a jinchuuriki (tailed beast host). According to this picture, he's the 5-tailed beast. They did this with the 3-tailed beast last year and late 2008 (which for whatever reason, was freed from it's host). I guess it's a spin off storyline from just some fold out picture in the manga featuring all the jinchuuriki that Akatsuki were targeting.
