I looked at the information, and it says I get a sticker every level up. I’m level 22, and I still only have the Tweedle, Mammott, Toe Jammer, Noggin, and Potbelly stickers! Is this because I started playing the game before the stickers were made? How do I get the stickers? I should have more by now. Is it because my account is Game Center? If umyou know the problem, please tell me.
