The Poptropica Tips & Tricks app just got a little more helpful. With a new update, now you can get walkthroughs for our two newest adventures, S.O.S. Island and Ghost Story Island!
Visit the App Store or Android Marketplace to download the update, then launch the app. The guides for S.O.S. Island and Ghost Story Island will now be in the list of Island guides for in-app purchase.
Download the iOS version of the Poptropica Tips & Tricks app from the App Store.
Download the Android version of the Poptropica Tips & Tricks app from the Android Market.
I am so downloading this app. 😀
