After yesterday's update to Bad Piggies the Angry Birds are getting their own back with new content for Angry Birds Seasons hitting the App Store next week.

The Abra-Ca-Bacon update brings with it 30 new levels, as well as 6 secret levels to try and unlock, and a whole new way of killing pigs – portals.

These magic tunnels suck fowl and debris in at one end before spitting it out somewhere else. Like the Portals in Portal, basically. But with pigs, birds, and crumbling lumps of masonry.

It won't cost you anything to get all this extra content, and it'll go live on the App Store on May 16th. You can check out a trailer for the new goodies below.
