Remove cake from store-bought packaging. Featured is a 2 layer, 7" white on white cake.
Divide vanilla frosting into two microwave-safe bowls.
Add orange frosting to a microwave-safe bowl.
Microwave each for 20 seconds.
Add neon coloring to each vanilla frosting bowl and mix.
Using a small spoon, carefully add the drips of the green icing to around the cake top edge making a drip effect.
Repeat this action with the purple color.
Swizzle the orange frosting across the top of the cake.
Using a pastry squeegee, smear only the top surface to mix the colors around. Be sure not to disturb the drip effect.
Once frosting is complete, it is time to decorate with the gumballs.
Strategically place white gumballs by carefully pressing them into the cake's frosting; repeat with the orange gumballs.
Next up, evenly place the green and purple shimmer Sixlets around the cake.
Next up, fill in the emptier spaces with the candy eyes, and then black pearls.
You can add plastic (non edible) spider effects to the cake (optional)
