In an underwater scene, a tall green plant grows rapidly upward from the ocean floor, passing over the tops of a pineapple house, a stone house, and a dome-shaped house. The plant continues to grow taller until it extends beyond the top of the frame. In a separate scene, a group of students are seated at tables in a school cafeteria, with some students looking down at their phones or talking while others stand in line at a counter in the background.
