First, you have to collect all 5 pieces of the dragon drawing. Then, rearrange the locks features to match the drawing.
go to the end and at night if you got all pieces go in the tunnel and climb the ladder and click the door or somthing then make the thing as same as the pieces.
the guy is beside the fishing boat but first take the tour inside the tunnel and exit from the door at the end>
If you have entered it from the tunnel system then you can exit it the same way. if you have entered it from the door you can use the door. if you need to get into the supply room you have to get a job first which means you have to talk to the assistant curator. once you get the job he will give you a key to the supply room. i hope your question was about counterfeit island. also i hope this helped.
you go out the door!
The bone is in a tunnel deep in the underground ruins. You will find it when moving left from the door with symbols on it. (see related question)
The Supply Room door has a key, which you receive when you get the museum job. The underground entrance is locked with the Dragon Face lock. The house in the Countryside is only unlocked later in the game when you receive the key.
You have to match the eight facial features of the paper dragon to the dragon on the top of the tunnel. It will take you to the supply room. - Good luck!!
go in thru the back door
you have to go to counterfeit island
In the Clown Shop.
go to the guy near the door. talk to him.
First, you have to find all the pieces of paper around counterfeit island. When the pictures are assembled together, it will show a picture of a dragon. Make sure the dragon on the door is the same as the dragon in the picture.
