Flying chops... that's how the meat-loving butcher considers the piglets in this game. They're very special piglets: they have wings and fly in the skies to save the pigs that have already been caged by the butcher. Bump into the cages to free the pigs and pick them up afterwards. Beware of the rotating knives, grab lots of acorns and hit as many balloons as possible! The better you do this, the more upgrades you can carry out.
Hold the left mouse button to fly upwards, release to descend.
