Angry Birds Rio Smugglers Plane Walkthrough Level 22 (12-7)
Smugglers’ Plane level 12-7 is very difficult. One strategy is to fire the first Blue bird into the far-right tower. If you are very lucky, the cage inside will break. Then lob the Orange bird so it lands between the first tower and the pink caged birds. If necessary, use the next Blue bird to clean up.
