Whoa, that statue does more than just sit there and store Bijuu. Soul eating dragon ftw!
I guess the lobster throne isn't just for decoration then. Looks like Nagato's legs don't work.
Kinda stupid though that Nagato could jump up there and save Konan, but he couldn't do it BEFORE Yahiko died.
Apparently it was a coincidence, since they didn't give it any significance. I guess it was just a way for Jiraiya to figure out Pain was using dead bodies.
