Poached Eggs 3-20 is the 20th level of the 3rd theme in Poached Eggs. The player is supplied with two White Birds, and three Black Birds.
Fire the first Black Bird over the first Small Pig. The force of the explosion should kill both the Small Pig and the Large Pig beside it. Use the next White Bird so that its egg and body both crash into the base of the 2nd smaller structure behind the first one, killing all pigs inside. Use the next 3 Birds to kill all of the remaining pigs and the majority of the Stone debris.
