Zynga knows that fans will keep coming for those game freebies. Today, it released a freePetVille Clean Bomb and a freeFishVille Maxima Clam on those games' official Facebook fanpages.
The Clam is a decorative item that's usually offered through the gifts page. It can't be resized, but it can be sold for 150 Coins and it's animated to open and shut while blowing tiny bubbles upwards.
To get your freebies, log into Facebook, make sure you're a fan of both games' fanpages, and click on the above "free" links.
