Theme 22-11 is the eleventh level of the last world of the episode Bad Piggies.
One strategy for Angry Birds Bad Piggies level 22-11 is to send the Yellow Bird directly at the base of the second tower. Debris should fall to the left, clearing the pigs on that side. Then send a second bird towards the top triangular block to knock the tower to the left. The resulting explosion should send the boulder down into the pit.
