This was for a 5 year old Birthday Party. She was having a swimming party at an indoor pool in the middle of the winter. It is a 10 inch cake with an in-ground swimming pool and waterfall. I used gumpaste for all figures and decorations. For the seaweed I used Fruit roll up and goldfish for the fish. For the water I used Hard Tac Candy. I was pleased with the way it turned out. At the bottom of the waterfall I crushed up the candy and spread it around the bottom to look like splashes.
