Participating games are CityVille, CastleVille, Words With Friends, Pioneer Trail, Bubble Safari, Draw Something and FarmVille, each with specific items to purchase for the charity, such as FarmVille's cheer-ewe-up horse for $1. As always, we're happy to see Zynga isn't sheepish about using puns. We're laughing so hard, there's a cramp in our calf. Sorry, we're really milking this one.
Some of the items have time limits within the charity drive, with FarmVille's ending on December 5 and Pioneer Trail's not beginning until December 17. Check out the full list of games, items and timeframes after the break.
