On the open grassland under the setting sun, two exhausted little boys lie on their backs, mouths wide open, tongues out, their faces flushed and covered in sweat; beside them stands a bald old man with a long white beard, wearing red sunglasses and an orange jacket, leaning on a wooden cane and smiling down at them. In the distance, the sky is colored orange and gold by the setting sun, gradually fading to a clear blue, while the grass glimmers with a mix of green and yellow hues in the warm light, presenting a classic 2D hand-drawn animation texture.
