Grease and sprinkle some of the cake mix in the bowl to prevent the cake from sticking. Prepare the cake according to the instructions on the box. Pour into the prepared bowl and bake using the longest amount of time on the package. Test for doneness by lightly depressing the center of the cake. It is done when the center springs back.

Turn the cake out onto a serving plate. Allow to cool thoroughly. Frost the entire outside with the prepared icing. Sprinkle with blue colored sugar or colored sprinkles. Arrange the gum drop leaves and red candy in groups of 2 leaves and 3 "berries" around the bottom edge of the cake.
