Mighty Hoax level 5-4 is deceivingly challenging. Our strategy is to loft the Blue bird over the main structure and pop the two pigs on the far side. Fire the first Yellow bird into the left tire, breaking the three wooden triangles on the left side. Fire another Yellow bird into the same spot, popping the well-guarded pig within. A large amount of additional damage is necessary to earn 3 stars, but this method is consistent for at least 2. The score in the video below is 71,320.

OK I’m off to bed here’s my final offering.First two shots as described but third lower due to undamaged triangle ,through top of bottom pig into bottom of right wheel.Everything collapsed to the left .Don’t know if I got lucky or if it’s a thing.All you Classic flingers need to come down here and duke it out.Bon chance my friends.
