The newest island in Poptropica is going to be called Mystery Island and it will launch on September 9. This island takes place in the late 1800s and you will go on a quest on board a train as it is heading for the 1893 Chicago World’s Fair. There will be a lot of famous people on the train along with a villain who is trying to ruin the World’s Fair. It will be up to you to uncover the plot and save the World’s Fair. Members will get to play the new island first and non-members will get a chance about a month later. Everyone can play the D.C. Diner game now, which is a mini-game being used to promote the full island.
