Ah, the action figures. I LOVED collecting action figure packaging when I was a kid, especially TMNT figures. The toys I played with, but I loved looking at all the little tidbits on the back of the box. I actually still have a whole box of 'em somewhere.
I didn't even know there WAS a Mona Lisa figure. I knew there was a toyline based specifically on the cartoon, though; I had April's boss and a couple of the Neutrinos.
