If you include some sudden coincidences, such as the colorful footprints of the ducks that make drawing a unique memory, it becomes a one-of-a-kind art. It's a stroke of genius on the part of the cartoon's creators. It also tells children that the beautiful images in their memories may be the priceless art. It has nothing to do with anything else.
