Miiverse posts can be decorated with Mario Kart 8-themed stamps! In addition to the twenty-eight stamps the game starts you off with, you can unlock more stamps by accomplishing things within the game. Thirty stamps are unlocked by taking first place in a cup with a given character. Another thirty-two require you to defeat the first Developer Ghost on each track in Time Trial mode. That means you can have up to ninety Mario Kart 8 stamps to use for your Miiverse posts!
