pop art style illustration of a mouse in a deep bowing position, with front paws stretched out and head touching the ground, in a sincere apology pose. The mouse should be cartoonish with soft, muted pop art colors, avoiding overly bright or bold shades. The background should be simple and not overpowering, using pastel tones to create a calm, understated pop art vibe. The expression should convey humor and exaggerated remorse without being too vibrant.
