Video prompt: The gentle sea breeze tousles her curly hair as she reaches for a small, blue plastic bucket, its surface glistening under the midday sun. With a determined expression, she lifts the bucket, her tiny fingers gripping its handle tightly. She toddles over to a patch of soft, golden sand, her bare feet leaving tiny imprints behind. With a triumphant squeal, she flips the bucket upside down, patting its base with her chubby hands to ensure the sand inside is packed tightly. As she lifts the bucket away, a perfect sandcastle turret is revealed, and she claps her hands in glee, sending a small cloud of sand into the air. Nearby, seagulls call out as they soar above the sparkling ocean, and the rhythmic sound of waves crashing on the shore provides a soothing backdrop to her playful adventure.
