The best strategy for Poached Eggs level 3-5 is to loft Red birds onto the roof of the structure. After a few shots, a bird will break through the ice block in the roof and onto the TNT within, blowing the building sky-high. The score in the video below is 112,230.
Note: This level was changed in the Angry Birds v1.6.0 (Mine And Dine) update. The structure now has a glass roof instead of stone one.
If you don’t complete it with two birds it’s impossible to three star. The 3-star threshold has been returned to 89,000, so completing the level nearly guarantees 3 stars. For completeness, we include another video below exhibiting a different strategy.
