In a dimly lit scene, several plastic pumpkins with carved faces are placed on shelves. The plastic pumpkin positioned at the lower left begins to move steadily to the right. It travels across the bottom shelf and eventually reaches the plastic pumpkin on the lower right. The two plastic pumpkins make contact, producing a gentle collision that pushes the right plastic pumpkin slightly further toward the edge. Both plastic pumpkins remain next to each other after the contact, while the plastic pumpkins on the upper shelf remain stationary throughout the sequence.
