A pumpkin shimmering in the moonlight attracts the attention of an owl, a cat, crickets, a witch, and a group of boys and girls, who change it into a scary jack-o-lantern.
A young boy watches as the seeds he plants in the garden grow into a riot of colorful pumpkins and squashes and are carved into jack-o'-lanterns with unique personalities.
One by one all the other pumpkins are chosen to become jack-o-lanterns, but even though no one buys the Littlest Pumpkin, its Halloween dreams come true.
