11X15 - 2 cake mixes. Water is Wilton Sparkle gel - looks great but tastes - not so great. Even had it sloped for deep end w/ Candy necklace White is buttercram. Figures are all fondant. I put it together day before and fondant softened up because it was touching gel and buttercream. If possible - wait til last minute to add fondant items. Still turned out good and kids loved it. I made enough stuff so that all kids would get something and my birthday girl (5yrs) and my 7 year old son helped too.
