There was no demo. There was a game called "Spook Central" that featured a hunt for ghosts on 5 other islands. It was discontinued when the island was released.
(see related question)
go to cheats of poptropica in ghost island
The net and files are part of the demo. You don't get them on the island
The full island is out now. Just get a Walkthrough for the island.
The island was opened to paid monthly members on December 15, 2011, and open to all on January 12, 2012.*Non-members could play the demo beginning December 15, but could only play as far as acquiring the ghost hunting equipment.
You could not "beat" any of the demo of the island. The quest stopped when you were shrunk, and you could not go right into the apartment. (see the related question)
The plasma net was a feature of the Spook Central demo game form November 2011. It was replaced by the full island Ghost Story Island in January, 2012, and has not been available since that time. Only paid monthly members could complete the game, which involved capturing ghosts on 5 different islands (not actually the islands used in regular play, but truncated versions of them).
Hey! I have played this demo millions of times, died, and have gone back to the beginning. I guess just collect as many heart capsules as you can, and try to level up without dying!
you cant........ you can only download the demo
you can't the demo past if the island is already there but you can play the demo on new islands.
In the demo for the island, players could look around through the viewfinder overlooking the Loch. Some would see a shadowy shape of Nessie, and win Cryptids costume items. (see related blog link)
*During Early Access, players who were not paid monthly members could only play a demo form of the island. The demo closed with the release of the island on July 28, 2011. The demo only took the player up to the point where he/she was shrunk by the Shrink Ray in C.J.'s apartment. (see the solution at the related question below)
No. The Island Map is no longer interactive except to show when an island is in Demo mode (usually during Early Access for paid monthly members). Islands converted to the problematic new 2013 look will be in color on the map.
