apparently it works by having a chance to receive a shiny one when you buy one, but after buying a normal one you can just buy a shiny one outright if you want. I greatly appreciate them not encouraging people to gamble and buy like 20 of them for a recoloring.
It's also just a chance to buy the older ones like the noomba again
