So the Toy Pieces in the Anniversary Event can be used to purchase exclusive toys from the Dormunstrad 2019 Location. Once you have all 3 toys, and if you're like me and grind every mini-event each day, the toy pieces are pretty useless, and it's impossible to resist clicking the green sparkles. Sure, you can sell them for gold on the marketplace, but that can be inconvenient once more people have all the toys. Long story short, a system to trade the toy pieces for event tokens would be super useful! I don't know what the ratio would be but I'm not really in a position to make that decision :')
