Watch out Angry Birds. Those Bad Piggies are hogging in on your territory.
Borrowing from the Bad Piggies game released a couple of weeks ago, the new levels prompt you to build various contraptions to coax the pigs along from start to finish.
The game's Surf and Turf level has also been spruced up with 15 new levels, each with the usual arsenal of sling scopes, king slings, and super seeds to give you a helping hand.
The update is free for existing Angry Birds owners. People new to the game can download it from the App Store for 99 cents or from Google Play for free. The Angry Birds HD edition at the App Store doesn't yet offer the new levels, but hopefully that version will get updated as well.
