There is no way, and fortunately it isn't necessary to do so.
Find the six pieces of the dragon face picture. (Top of the boat mast, sand next to the gate at the docks, top of the museum, right side roof of the Inn, the supply room, and the one you didn't get, which is in the domed area of the underground, above the hanging bulb.)
Match the face on the lock to the picture (there are 8 separate facial positions to match) and you enter the Supply Room.

you go back on counterfeit island
If your talking about Counterfeit Island then you get the key and go back to the museum on Counterfeit Island
Once you get the key from the curator, go back to Counterfeit island and use it at the Inspector's house.
The underground dragon piece is under the dome in the Underground Tour. I do not know if you can get it in the morning on Counterfeit Island--I always get it at night. Anyways, you pass the dome and it's near the front. Well, if you get it in the morning it's near the front cause you took the tour, but if you get it at night it's near the back--But in the same dome! So I hope that helps. ~An Answer
go in thru the back door
The art thief is back on Counterfeit Island. As part of Counterfeit island, you don't need to do anything in Early Poptropica except get the key from the curator at the Pop Art Museum, then return to Counterfeit Island to open the Inspector's house.
you have to go back to counterfit island and go to the country side.
All you do is enter the Pop Art Museum and meet the curator at the bottom left inside. Then you go back to Counterfeit island to finish the quest.
