Besides my Lanny McDonald jersey... it would be my Masters of the Universe fortress. There was an epic battle between Prince Adam aka He-Man and the sinister Skeletor that day.
I think Green Lantern made an appearance too, he seemed to always find his way into my battles.. no matter which toys I was using.
Snake Mountain! That is what it was called.. thank you google.
When I look back on it now.. it sure doesn't look like much, but trust me, there was many battles fought here.
