Our strategy for Ragnahog level 21 to get 133430 using all four birds is shown in the video below.
Little Red is batting leadoff again. We send him in a medium arcing shot to the second shingle on the left side of the roof, causing a surprising amount of damage as the roof collapses inwards. Stella steps up and flies a bit lower to the stones next to the stove, activating on impact. Stove blows, piggie goes. We send chuck high to the remaining structure and directly through the left horn on the helmeted pig’s head, literally blowing his mind. Up steps Matilda in the clean-up position, and clean up she does! Low arc to bomb the right side of the sled and ricochet not-a-carcass up into the remaining upper pig. The collapse of sled finishes of the two pigs there.
