If the Fairy Garden theme of items in the FarmVille marketplace isn't enough to tickle your imagination, and you also happen to have quite a bit of Farm Cash lying around (just begging to be spent), you'll be happy to know that Zynga has updated the Mystery Game this evening with a new set of fairy-themed animals.

The Mystery Game costs 22 Farm Cash to play this week, and comes with the following items up for grabs:

Fairy Deer
Fairy Rabbit
Mini Pegasus
Mini Unicorn
Mouselope
White Dragon

If you're lucky enough / willing to earn all six of these items before the game's week is up, you'll also win a seventh bonus prize for free: the Fairy Dog. Remember though - this bonus prize is like all of the others; it will only be around for a week. You'll need to shell out quite a few Farm Cash (even if you're lucky enough to win these six items quickly) to earn it, but if you do, you'll have bragging rights for quite a while, I can assure you.

Will you play this week's Mystery Game for fairy-themed animals? Which of the six are you most excited to win? Will you go for the Fairy Dog in this game? Sound off in the comments.
