Clams

Clams are the premium currency used in Family Guy: The Quest For Stuff. In the beginning of the game, when Chris is found, he explains that in history class, he learned that Clams were used as special money, and that they're magic and used to speed up time. Clams are used to buy premium items in game such as Barrington Country Club, the Church, Consuela's House, Quahog Derby Stables and much more. You can also use them to upgrade your Worker's Bunks to unlock another worker. To get more of them, you can visit your friends, complete special quests, or buy right from the game shop for real money.
