Millions of Unusual Small Creatures Lurking Everywhere. Tiny, 2" wrestling monster figurines in molded pink PVC gum, based on some Japanese anime or something. I really liked these things when I was 8 years old, and here they are again. My favorite was this little mohawk dude I called "Little Joe":
And apparently they were also available in other colors, although I only remember the pink ones.
I also really liked the M.U.S.C.L.E. Nintendo game. One of the better wrestling games out at the time.You can get more info on these guys on wikipedia here: http://en.wikipedia.org/wiki/M.U.S.C.L.E.
