Island Medallion

The Island Medallion, or simply called Medallion, is a medal given to you as a reward if you complete an island quest. The Medallion comes with 150 free credits (originally 100 and later 50), and can be worn by the Poptropican.

Islands
The only way to earn the Medallion on each island is to complete the quest. Each island has different ways to complete the quest.

All the medallions belong to someone else before you got them.

Credits
When the player completes an island quest, the reward is 150 credits as of summer 2015. Prior to late 2011, the award was 100 credits, and between 2011 and 2015, the reward was only 50 credits.

Restart
Starting July 6, 2011, Poptropica started allowing players to replay islands, while keeping all the Island Medallions they had already earned. The medallion they received from completing once will disappear from their inventory, but not their friend's page. However, they will not receive credits on replays.
