Well, I had something really strange happen to me tonight...
I was re-arranging my display shelves and while I was moving some stuff around, I noticed that my Droids R2-D2
bubble had completely detached from the card. Since it was in an Oscar case, it wasn't noticable until I grabbed the case to move it and the bubble tipped right over in the case.
I tried in vain to re-attach it, but failed miserably. As a precaution, I went back through the other 9 carded figures I have and they all seem to have nice firmly attached bubbles. I have no idea what could have caused R2's bubble to pop off - just a weak glue job I guess.
The thing that was so strange about it was that I had been going back and forth about dropping the cash for another one to open to go with my Droids 3PO, so in a way, I guess fate made the decision for me.
