What happens

Lisa Simpson, the girl with star-shaped spiky hair and a red dress... wait, in these frames she wears a white pearl necklace and a yellow dress, with wide-eyed, grimacing expressions, appears in the lower right and later close-up, staring in alarm beside blue pipes in a factory setting. Above a blue wall, large grey gears with spiked teeth turn at the top of the scene, while a molten orange substance pours out of a grey chute with a round opening and flows down a zigzagging purple channel lined with dark green brick. The orange flow slides steadily downward and to the right, and Lisa's mouth opens as she gasps, with the on-screen moment ending on her wide-eyed face.
