So I try and try to name my creatu and I click the finish hatching button. NOTHING HAPPENS. Can someone please help me with this problem. I and ignorant to this site and new. Help needed.

Is the name available? It should be one that's not taken and doesn't have any funky symbols like $&% and that kind of stuff. If the name is available, the naming box will have a green outline, and a red if isn't. If the outline's green, you should be able to click the finish hatching button just fine. =)
