What is the full error you are getting. Just posting 400+ lines of code and a partial error message as your title generally doesnt get you very far.

[Ancient Dragon]

Those kind of errors nearly always means you didn't implement one or more of the class's methods. If you think you did, then it may be a spelling/capitalization problem. The error message will tell you which method you failed to implement.
