MediaWiki:Description

Poptropica consists of several islands between which the character can travel. Each island has its own quest, which players are encouraged to complete. If a player completes an island's quest, he or she receives an island medallion as well as 50 credits to spend in the Poptropica Store. Starting July 6, 2011, Poptropica started allowing players to replay islands, while keeping all the Island Medallions they had already earned.
