If you are asking what island is next on Poptropica, I believe it is Reality TV Island.
There are many islands of poptropica
The next island migh be a tropical island in the sneak peaks.
On the Poptropica blog, I think they say the next island is Pop Island ***ALOS ANSWER!!*** There is no pop island as you can plainly see so
wimpy wonderland island
The newest island on Poptropica is Red Dragon which is opening soon. (I have no idea when, sorry!)
After the Astro Knights island release in June 2009, the next regular feature was Poptropica's Haunted House in October 2009. (Available through the Poptropica Store) The next scheduled island was Counterfeit Island.
Mystery train island
The next island poptropica says is about ghosts
The island after Super Power Island was Spy Island.
The next island will be counterfeit and this island will come out on the fourth of January 2010.
When you finish poptropica just wait for the next island to come then you are not finished
