AAAAAHhhhhhhhh!
They're here in Indianapolis! Finally!
I was poking aorund in the Target store (which is just five minutes from my house) and they had the 5" figures, the turtle shell, and the RP toys there. Woohoo! Unfortunately, it was just the turtles left. It's been hit by many other buyers too, I guess. I bought Donny for now... but will go back to get the other three.
