This was for my son's 5th birthday and was a real crowd pleaser. The body is cut out from a 13x9 cake and the head was formed from the scraps. I made 1/2 batches of red, white and blue MMF. The yellow accents I colored from the white MMF. I stuck Autobot rings on the arms rather than trace the insignas. No icing (except a crumb coat), only MMF on the entire cake.
