Witch about to be burnt at the stake cake

Grey fondant meant to be old town square, black fence is paper Halloween cupcake wrappers. Fondant flames, witch is made from marzipan, stuck between 2 ice cream cones, one like a well, the other turned into black hat. If she can turn herself into a frog she'll escape! Inside its carrot cake, but cut into it to insert orange sponge pumpkin shapes and mauve sponge bat shapes!
