meet the man near the exit of the cave and the ladder inside will get acess to the supply room in the museum
To get out of the tunnels into the museum after dark you most go through till you see a slightly broken ladder, go up that and then your in the museum.
You click on the dark side of the moon.
You encounter him at the end of the Underground Tunnel Tour. He tells you to get the museum job. When you get it, and return after dark, he sends you to protect the famous painting from being stolen. (This does not work out so well.)
It needs to be dark
In the Main Gallery at night, all you can do is click on the painting "The Scream".
it depends what island you are talking about but if it is early poptropica then it automatically equips when you go in dark places if not sorry idk
After identifying the thief and chasing him on the scooters, you get a message signed, THE CURATOR. Go to the Pop Art Museum on Early Poptropica and find the old lady, who will give you a key. Then go back to Counterfeit Island, to the house in the Countryside. Open the door and go upstairs, and click on the painting. The room will go dark and you will awaken with the Black Widow, and you are tied up next to the guy with the scar on his face. Once she leaves and you find that he is willing to help you, drag your chair over to him and he will untie you. Go through the lair and sneak past the guards, and use the key card to reach the treasure room. Save all the falling artwork and crank the lever. When you have won, you will be in the coffee shop with the Curator. Meet her back at the museum and she will show you the museum's secret, and give you the Island Medallion. (see the related question)
I think it's between the dark room and the pit if thats what you mean.
there is a light switch next to the ladder click on it and it won't be dark any more
The caves are dark tunnels underground at Poptropica Towers (far left of the island). The purple giant's Golden Egg is in the maze of vines and tunnels.
Click on the Moon : the photo must be fake because you can see through the dark part of the Moon.
You go up to where the moon is, and click the dark side of the it. It says that the dark side of the moon should block your view of the stars, but you can still see them.
