Good game; problem with achievements. – Flea Symphony Review

Love the game, and have completed all levels with golden notes. There are two achievements that appear to be impossible: Share your progress on Facebook and purchase Iso and the Triumphant Triangle. You can tweet, email, and instant message, but there is no FB interface. What is Iso and the Triumphant Triangle? Is is a separate game, an in-app purchase, or what? There is a way to restore previous purchases, but there is no way to make new purchases.
