Fans of Bad Piggies will be happy to know that Rovio had released a cookbook featuring their favorite foul swine, and the 2011 book has now been made into a handy app!

Bad Piggies Best Egg Recipes is now available for your iPad. The virtual cookbook is celebrating its App Store debut by having a launch sale for only a buck! The 264 MB download has 41 different egg recipes you can make, with animated illustrations, step-by-step photo instructions, photos of the finished recipes, a convenient egg timer, virtual bookmarks, social integration and more.

It's a pretty cool app for cooking buffs and the added Bad Piggies motif puts a little pizzazz into the dishes. Like we mentioned earlier, it's on sale for $0.99, so click to buy it for your iPad before the price goes back up to $4.99!
