A battle of pillows

Three anime girls are in a bedroom; one with red hair and a striped tank top sits on a bed, smiling and holding a yellow object, while a smaller girl in a pink dress lies on the bed between them. The scene cuts to a close-up of a blonde girl with a surprised expression, then to a close-up of an orange-haired girl with a wide smile, before a quick, blurry transition with red and pink lighting occurs, returning to the original scene.
