Birdday Party Cake 4 Level 13 is the thirteenth level of Cake 4 in Birdday Party.
There is only one strategy for this level. You just need to arc a Yellow bird into the wooden base of the right structure. This is a small window, but worthwhile. Falling debris can break through the ice blocks (if you want high scores, you must break these ice blocks with your bird before the right structure's debris so that the right structure can fall "nicely") and blast the TNT below.
