Theme 1-7 (AKA, "Due Castle") is the seventh level of "Poached Eggs". In a built up fortress is one Small Pig and two more up on the top on either side. The player is supplied with four Red Birds.
Three Star Strategy
The level can be completed by using only one bird. It must be fired at the Wood Block to the left of the center-most pig. This should cause the structure to shake, defeating the center pig, and causing the two other pigs to just roll off. The player will get 30,000 points for the 3 extra birds.
Theme 9-2 is an attempted reconstruction of this level.
