Star Walkthrough
Hit the Yellow Bird so he hits the top left snow structure so the rock inside can collapse on the one below.Then shoot the next one on top of the structure so the next rock falls on top so hit falls on King Pig. This may only slighty damage him but then the rock and himself will fall on the structure on the bottom right and the one next to it. Finish off the last section with the Yellow Bird. The two unused birds will award you an extra 10000 points.
