We show a 4-bird solution for 137720 in the 3-star walkthrough video below.
Haaaay! At least that’s what’s in the truck. That balloon there is holding it up, so we target that with a low blue and early split, taking out the mailbox and popping the balloon, allowing the truck to slide forward. Next chuck goes in a medium arc over to the barn, through the lower left glass panel, opening up a hole for later. Send Big Red low into the remains, he’ll cut through the truck and clear the rest of the left side. Finally, Bomb Bird into the hole created by Chuck to take out the barn and toss debris onto the remaining pigs at the far right.
Feel free to leave comments below, but don’t just post your scores – that’s what the leaderboards are for.
***This level must be played in airplane mode. Otherwise, the annoying continue playing offer will appear no matter how many birds are used.***
