Grapes

Grapes are the main focus of, and is the only food that appears in, all 3 videos. Despite being mentioned on several occasions, they only have one physical appearance, and it comes at the end of the first video when the lemonade stand man takes the duck to a store to buy them. After he eats one, he despises them and asks the man if he thinks the store has any lemonade instead. They come in a purple box and are purple in color.
