Thanks to customcakesbysharon for the idea for this cake. This is only the 4th cake I've ever made. bottom is 10" round rice krispy treat. Top is a wonder mold. I put barbie on top because I didn't feel confident in my skills yet to make her tail. Seaweed, fish, starfish and coral are MMF. Shells are royal icing and purple grass is buttercream. Icing was too soft and wouldn't stand up. I'm definetely still learning.
