I am making the cake for my cousin's baby shower and I am trying to figure out how to make bubbles to go around the rubber ducky cake. This is what it is going to look like http://www.wilton.com/shapedpan/3-D-Rubber-Ducky-Pan (The one pictured right by the pan) I want something to put around the base of the cake to look like bubbles and maybe water. Preferably edible. The only idea i have so far is to make balls out of white fondant and place them around the duck. Any ideas or suggestions?
