I first saw pics of some Mighty Muggs online awhile ago, but only recently did I actually see them in stores, so when I saw the only Galactus figure on the shelf, I impulsively bought it. Thing is, when I unboxed it and started messing around with it, I noticed the head swivel and one of the arm joints were kinda loose. Like, they were just really easy to move/swivel up and down (to be clear, they weren't coming out of their sockets or anything like that). Is this typical? The other arm is pretty stiff, and I like it like that, but should I be concerned w/ the looseness of the other joints? I mean, I don't intend to "play" w/ the figure (just a little knick-knack to put at my desk really), but I'm still kind of worried that if I mess around with it, something might accidentally pop out or something.
