Each username can only get credits from each island once, and points cannot be transferred between usernames.
You receive 50 credits for completing an island, and 25 credits for finishing the free mini-games Haunted House and Earth Day, which are in the Poptropica Store. (The mini-game Dr. Hare's Secret Lab actually costs you credits, 250, and only awards 25.)

If you start off with no credits, then you have to buy the credits. I think $20 gets you 2000 credits. If you already have, let's say, 500 credits, than you have to buy more credits, also. You would need 1,500 credits, and 1,500c=$15.00
