Other people probably have children who beg for "normal toys". My child begged for a gas mask that he saw on Etsy. He kept coming up with practical reasons why he would need it, like so he wouldn't be breathing all that dust when a big bus drove past us as we were walking on a dirt road, or when campfire smoke was blowing in his direction. I don't think this pretend gas mask will really help in either of those situations, but it looks pretty cool in a dark room, if you don't stare directly at it.
So, yes, I gave in. After months of begging he has a gas mask that flashes multiple colors.
This is the video that convinced him that he had to have this flashing, dance party gas mask:
