Where is the museum on Poptropica?
Well there is 2 museums in poptropica.
1. There is a sight seeing museum in Early Poptropica Island.
2. There is a museum in Counterfiet Island, which the scream is being held.
Hope this helps!
On Counterfeit Island, the curator of the Museum Fantastique summons you to meet her on Early Poptropica (an extraordinary inclusion for Poptropica). Take the blimp to the other island, and enter the Pop Art Museum there. After meeting the curator, return to Counterfeit Island to continue the quest.
