I made this cake for a church friend's son for free. They wanted a Spongebob underwater theme. I used a 13x9, yellow cake iced in vanilla buttercream. Spongebob and Patrick were made by made oldest daughter with MM fondant. (She has the talent!) Edible marker was used on Spongebob & Patrick. I made the mmf coral, clamshells, rocks and flower pad they are sitting on. Edible pearls inside the clamshells. Yellow flowers are piped buttercream.
