Angry Birds fans who worked their way through the Angry Birds Trilogy and are craving some more fowl-tempered thrills can now enjoy 135 new levels.

The hugely popular Angry Birds Trilogy just got its second add-on content pack, adding 135 new levels to the mix.

The "Fowl Tempered Pack" launched on Friday, March 8, and is available for the Xbox 360 and PlayStation 3 versions of the popular game. The add-on pack features 135 new levels based on the mobile game episodes Bad Piggies, Back to School and Haunted Hogs. With the new Fowl Tempered Pack, players also get access to Stella, the Pink Bird that can trap enemies in bubbles.

As previously mentioned, this is the second DLLC for Angry Birds Trilogy. The first one, the "Anger Management Pack," arrived back in December with 130 new levels and the Orange Bird. The new Fowl Tempered Pack is now available for 400 Microsoft Points or $4.99 in the PlayStation Network.

Angry Birds Trilogy made its debut back in September for PlayStation 3, Xbox 360 and Nintendo 3DS. The bundle includes Angry Birds, Angry Birds Seasons and Angry Birds Rio. Last month, Angry Birds creator Rovio announced that Angry Birds Trilogy sold more than one million copies worldwide since its launch, further increasing the popularity of the addictive franchise. Versions for the Nintendo Wii and Wii U should become available later this year.

Meanwhile, the iPhone and iPad versions of Angry Birds are currently available for free in the App Store. The iPhone version was previously on sale for 99 cents, while the iPad version came with a $2.99 price tag. It is unclear at this point just how long the games will remain free in the App Store, so those interested should grab it while they can.

Although Rovio made the game available for free in the App Store, the console version of Angry Birds is still a paid game. In other news, Rovio also launched Angry Birds Space on Steam for $3.99. With such offers and additions, it makes sense the popularity of Angry Birds keeps surging, doesn't it?
