Space Boss Levels

Following the success of boss fights in Angry Birds Rio. Angry Birds Space brought back this kind of system starring the Bad Piggies. Unlike the bosses in Angry Birds Rio where all of them only moves avoids the attacks, most of the bosses in Angry Birds Space are given ability to attack the birds by creating obstacles. Almost all of the bosses are King Pig riding several types UFOs with it's own attacks, strategy and methods. Each bosses are given 5 hits except Robo-Pig Saucer who only takes 3 hits and UFO Miner that only takes one hit. Smaller episodes such as Fry Me to the Moon and Solar System doesn't play boss theme at the end of the level. The only episode that doesn't feature any bosses are Danger Zone as the episode itself is incredibly hard as boss levels.
