To get the museum to let you in on Counterfeit Island, you have to go through the Underground Tunnel, then exit the tunnel, where it leads you to the City Docks. There will be a man waiting near the exit and he'll tell you to get a job at the museum, then meet him at night. You go to the museum and tell the guard you're there to apply for the job. He'll let you in the museum.
There is security lighting in the gallery itself, notably above the painting "The Scream".
At night, when you sneak back into the museum, that is your plan to catch the thief. It does not work.
The Van Gogh painting "Starry Night" is on display at the Museum Fantastique, but also at the Pop Art Museum on Early Poptropica island. One or both are copies, but that does not affect the game play on Counterfeit Island. The artist Vincent van Gogh (1853-1890) is there at the Pop Art museum (probably an actor).
you go to the pictures and the onr that i mean is the picture called the scream and click and you'll see what happens
Although you enter the museum to protect the painting, you are arrested for trying to steal it (and so it gets stolen anyway).
When you enter the museum and night falls, he probably goes to sleep at the Inn, and he is gone the following day.
You go in by the tunnel.
