Theme 22-8 is the eighth level of the last world of the episode Bad Piggies.
One strategy for Angry Birds Bad Piggies level 22-8 is to send the Orange Bird directly against the first structure, and trigger upon impact. Debris should clear the pigs on the left. Then send a second bird towards the top pig, and trigger upon impact. With some luck, debris should detonate the TNT below, clearing any remaining pig.
