used the wondermold and added an add'l 8" round below, BC icing and I made the seashells from Vanilla Candy Melts and purchased the Seashell shape tray Very easy and fun to make! The Seaweed is just also tinted Green Candy melts I just drizzled/spread on parchment paper...Ariel was to pretty to shove in the cake so I opt'd to sit her on top! She was a Hit at my daughters 1st Birthday!!
