Word that Rovio Mobile was stuffing its yuletide Angry Birds update into its Halloween version of the game [$.99, HD] struck us as odd. Sure, Halloween is a "seasonal" offering, but these two holidays are complete opposites.

This thought must have occurred to Rovio as well because the update, which does indeed add several new snow-laden levels to the game, adds more than just Christmas cheer: It also rebrands the Halloween to "Angry Birds: Seasons," killing the current confusion and thereby nipping all future hullabaloo in the bud.

The Christmas-themed episodes are packed within the App under the heading "Season's Greetings," while the Halloween stuff has been moved to another episode called "Trick Or Treat." Angry Birds Halloween is still $.99 for the iPhone and iPod, while the HD version for the iPad remains at $1.99.

Having spent a few mind numbing minutes with "Season's Greetings," we can say that we fully endorse Rovio Mobile's attempt to get us in the seasonal mood. Plus, it's free, so complaining would be a bit silly. Download this update as soon as you can.
