Fruit Cake (Fresh Fruit in the Shape of a Cake)

"I made this "fruit cake" for my husband's birthday dinner, as he is not fond of cake. This "cake" is made entirely of fresh fruit, which is cleverly arranged in the shape of a cake (basically a carefully arranged fruit salad). It was a big hit with my hubby and the rest of our family, especially the kids. It's healthy, people can pluck off whatever fruit they desire and cut whatever size slice of watermelon they like, and the types of fruit used are interchangeable. Creative substitutions are welcomed! Enjoy!..."
