FarmVille Sneak Peek: St. Patrick's Day treehouse coming soon?

If this newest batch of unreleased images in FarmVille is anything to go by, it looks like Zynga will be carrying out this year's St. Patrick's Day celebration in two parts, just as it did for Valentine's Day this year (with the Cupid's Castle and the Valentine Mailbox). While we've already spotted an image of the interior of this year's St. Patrick's Day Wishing Well (which will apparently act like the Valentine Mailbox, but require you to complete collections with items in order to earn better prizes), we've now discovered what this holiday's equivalent of the Cupid's Castle will be - that being a grand treehouse.

This treehouse starts out as a simple hoe with a small tree sprouting out through the roof. By adding three three buildings materials however (Bricks, Boards, and Nails - see below), you'll be able to upgrade this treehouse a total of four times, until you have an item that has the home perched high in the trees, surrounding by foliage and even a lovely rainbow.

It's presumable that this item will function it the same way as the Cupid's Castle, allowing you to "harvest" from the building to collect items - likely the Lucky Pennies we showed you earlier - which can then be traded in for prizes in the Wishing Well.

More details on this new building item are forthcoming, and we'll make sure to bring you all of the details about this new feature as it launches in the game.

In the meantime, let us know what you think of this prospective collection feature in the comments.
