COPPA should lift as soon as you turn 13, so if you're over 13 and still under COPPA you probably have the wrong age on your account. You'll need to send in a COPPA form to get that changed - one would have been sent to your email when you signed up/were COPPAed, or you can contact coppa@chickensmoothie.com to get a new one. :3
Cute hedgehog, by the way! ^^
