Faith and Begorrah! Rovio is adding some more holiday themed levels to its massively popular Angry Birds application, just in time for the holiday that marks my favorite day to enjoy a Guinness.

Sometime in the next few days, we should expect to see the Saint Patrick’s Day addition to the Angry Birds Seasons application hit the Android Market. No word yet on how many levels will be added, but if the Valentine’s Day addition is any indication, chances are we’ll see another 15-20 or so with the Saint Patrick’s Day update.

Stay tuned to Rovio’s twitter account and/or Android and Me for the latest and greatest info on when these new levels become available. Meanwhile, check out Rovio’s teaser video below.
