The anger of these birds knows no bounds, be it the holiday season. Halloween is just around the corner but despite that, these birdies are looking for some destruction pitting themselves against their lifelong rivals, the evil pigs. They have ensconced and hidden well behind wooden walls to protect themselves. Don't let that stop you and fire those birdies like there's no tomorrow. Each bird has its own unique ability. Take for instance, the red one can boost its speed in the middle of its flight. Black ones will detonate themselves like a bomb. Whilst blue ones can split itself into three midget birds. The key here is knowing how to accomplish your objective with the least use of birds.
