This little snorkeler will go over swimmingly at any birthday party.

Layer and frost the cakes.
Unwrap the Kisses and place them around the top for hair.
Add the LifeSavers and M&Ms for eyes, a licorice mouth, and a gumdrop nose.
Remove or unfasten the strap on the diving mask, then place it over the face and lay the snorkel next to the cake.
