Fail!!! Why not all tiles can be used as keychain?
"Only the black tile has the chain and the others not? Who designed this and why? Why do you offer 9 colorful tiles when only 1 can be used? It does not make any sense!!! How can I use all other tiles as key chains? In the manual/box there is mentioned the possibility to buy additional product 853902 to have more key chains, but I do not want those neutral-colored tiles with eyes on, I want to have colorful tiles in this product! Or I can buy just 1 piece of key chain (850152) for another 5 EUR? You cannot be serious. Real fail, Lego."
