Alien Flea Market...
I know a flea market is a place where second hand goods are sold, but the alien part is strange for me. Maybe on another planet you can have an alien flea market but not on this one, I'm not sure we have the presence of aliens here on earth.
Or maybe the prompt can be said that aliens are sold in this particular flea market. But ofcourse, we would have heard of it because there will certainly be an interference with the government and basically an explanation about where the aliens came from.
Overall, I don't think it is a good idea to have an alien flea market at all. It is dangerous and quite reckless too, the normal flea market is good.
