I have no idea if this is in the right place, but im desperate. I want to give my son an old lego set that was one of my favorites, but im missing these two legos, i managed to find an old picture of it, but i have no idea the names. The first is a yellow square, golden almost with a skull in the middle, the other is a triangular iridescent green brick, like a jewel, can someone help, or at least give me the names/sets these belonged too? thank you all so much!
