I recently acquired a few pounds of LEGO with some off-brand building blocks mixed through it. I've got three mystery pieces that I haven't been able to find on Bricklink. I'm wondering if they are Lego or off-brand pieces. I was under the impression that most LEGO pieces had the word LEGO written on them, and none of these do.
Brown hair: Has the number 5 on the bottom. It fits a 2x2 square. I got no matches in a search for "hair", filtering to brown color.
Green gem: It kind of reminds me of Rock Raiders, but I got no matches for "green gem" or "green jewel". The base is a 2x2 circle. It has no lettering on it.
White "wings"? This one I am quite sceptical of, however it fits perfectly on a minifigure as a pair of wings. I had no idea what to search for this one. It has a number 2 on it.
I'd like to know if these are Lego pieces. Reasons that they likely aren't (eg. LEGO has never used that color) are great too.
