The film tells the story of Alexander, an "itty-bitty" grape who lived in the middle of a bunch of grapes in a fruit store. Feeling threatened by Freddy the Fierce, a towering watermelon, Alexander wishes to be a watermelon himself. He goes to the library and studies to reach his aspiration, and after transforming into several larger fruits, he finally becomes a watermelon. Alexander returns to the grocery store to square off with Freddy, but just before their duel, a lady takes Freddy away for dessert. Alexander is left to realize that life as a watermelon is far lonelier than life as a grape in a bunch. He turns back into a tiny grape again, and the story ends happily with Alexander aging to a ripe, old raisin.
