Angry Birds Rio Smugglers Plane Walkthrough Level 21 (12-6)
A simple strategy for Smugglers’ Plane level 12-6 is to fire straight ahead. Launch the first Black bird into left side of the first structure, blowing it to smithereens. Fire the Orange bird through the wooden wall of the next structure, expanding within to blow it away as well. Finally, launch the last Black bird into the next structure to topple everything rightward. If necessary, you have a White bird to bust any pesky cages.
