Decorate cake. Place cake on cooling grid over baking sheet. Pour white glaze over entire cake. Pour pink glaze over 1/3 of cake. Pour purple glaze along line where pink and white glaze meet.
Using angled spatula, gently swipe tinted glaze at a slight angle, allowing it to drip off the cake. Chill until set, about 15 minutes. Using spatula, remove drips on bottom of cake; place on serving plate.
Sprinkle tinted side of cake with nonpareils. Arrange candy balls, gumball, chocolate candies and bark on tinted side of cake.
Helpful Hint: If you can’t find silver gumballs, you can use Silver Color Mist Food Color Spray to tint a white gumball silver.
