Here's a list of the confirmed items that have been received when opening a Winter Whimsy box (turns out you won't have to wait until next week to get your hands on some of these items, like was first believed, as they are available right now - Snow Stallion and Ice House, I'm looking at you):
Large Can of Fuel
1/5 Can of Fuel
Yes, farmers, the Snow Stallion is available to receive from the Winter Whimsy box. I know this is difficult to believe, because the Snow Stallion will also be available for 500 presents once you overfill your Holiday Tree's meter, but we can confirm that the item is in the gift box, even if it is the rarest prize available, as some very lucky farmers over on the official FarmVille forums have been receiving them for themselves.
And there you have it! A complete list of items that you may win when redeeming for the Winter Whimsy box, giving you more than enough to go on to decide whether or not you think redeeming 10 gifts is worth the risk of ending up with just 1/5 Can of Fuel.

Will you redeem any of your Gifts for the Winter Whimsy gift box? If you receive a Snow Stallion yourself, we'd love to hear about it! Which other item would you most like to receive from inside? Let us know in the comments.
