When you get 100 credits and when you get a medal.
click on freinds at the top (picture of your character)
You know your done when you have collected all three items and given them to the civilians of the Old part of town. You go on the ship at the dock and you will get your island medallion. Thats when you know your finished with the island and you have beaten it.
There might be a few secerets there but as far as I know, I have not finished fixing the future yet so I do not know weather of not there are secerets but if there are secerets then I would be glad to find it because I have finished the early poptropica's and shark tooth's island's missions.
If you beat an island on Poptropica you should know you beat it because, If you beat it you should get a medal and a few coins! Hope that helps!
