Completly STUCK on Counterfeit Island poptropica...? - the papers in poptropica counterfeit

I had all the parts of the dragon on the island Poptropica forgery and now I'm in the work of the tunnel, what is missing, stuck and no way to get it because it is in the center or something that will be closed overnight. Any tips?
