FarmVille, as not only has a set of limited edition items been released in the game's store, but this week's Mystery Game is also stuffed full of themed decorations for use on your many farms. There are six different decorations up for grabs, including a gnome, with the full lineup being discovered by FarmVille Freak.
Fairy Garden Shed
Fairy Tree Castle
Spiral Shell House
If you're an animal collector, this game isn't a total wash, although you will have to spend plenty of Farm Cash (or use plenty of saved Mystery Darts) to receive the one animal available: a Rapunzel Pony being given out as a bonus prize for winning at least one of all six items above. Again, this is easier said than done, as duplicate prizes are definitely possible, meaning that even more Farm Cash will be necessary to walk away with all seven prizes in the end.
Remember, this set of prizes will only be around for a week, so you'll want to make sure and play this game as soon as you can if you're interested in any of the prizes therein. Good luck winning the items you're hoping for!
