Available birds: Froshh; Zzzt; BipBapBop
Number of launched birds: 2/3
Estimated score: 56000+ (+1x 10000) = 66000+
Launch the first bird in such a way that it hits the pig and flies inside the structure through the plank. There is no reference point here to help adjust the path, but it shouldn't be too difficult for you.
The second bird has to be launched much higher - the upper part of the structure should have been destroyed at least a little in the previous strike, making the second launch much easier. If it hasn't been destroyed, though, you can still try, as the bird will fly over the "spike" at a much stronger angle. Once you reach the indicated spot, change the course so that the bird attacks the mushroom; the whole thing should collapse.
