I used a half round cake pan and made one half out of cake and the other half out of RKT. The beak, feathers, and tail are fondant/gum paste mixture.The beak is heavy enough that I was afraid it might tear through the cake. The RKT seems to be holding it just fine. This was very fun and my first attempt at a round cake. I found a picture of this on the internet and just had to try it, as it was my son's 22nd birthday and he just LOVES to play Angry Birds on his phone!
