i made two round chocolate cakes for the bomb bird and two round yellow cakes for the yellow dart bird. for the bomb bird i just left them as circles and for the yellow bird i traced out a template and cut the cakes. then my husband and i made tons of marshmallow fondant from the recipe on here (thanks!) and started to dye it all the colors we needed then just crafted it onto the cakes. my husband is so amazing he pretty much made the whole yellow bird while i made the black one and there they are angry birds cakes =)
