WALL-E. My favorite Pixar movie. I find it funny that I get weepy during the scene when Wall-E and Eve are having their romantic moment while the other robots scatter off to give them privacy. I think the background music helps.
Why settle for a generic cake topper when you can create something truly personal and meaningful to you? Use action figures from toy stores and other creative sources for a one of a kind topper. Wall-E movie cake topper.
