I made this cake recently for a good friend for her child’s 4th birthday party. The theme was a Country HoeDown, so I used old wooden crates, denim jeans, bandanas and farm animals as my influences. The birthday boy also wanted the mooing tractor from Cars so I sculpted one from modeling chocolate. I put the sound module inside a tractor tire (also made from modeling chocolate) that sat on the cake board so he could get to it easier and play with it.
