Create an exaggerated caricature of Velma Dinkley. She should have oversized glasses slipping down her nose, a furrowed brow, and tightly pursed lips. Dress her in an orange sleeveless turtleneck top and a pleated skirt. Style her hair in an exaggerated bun. Her stooped posture should hint at the burden of her intellectual pursuits. The image should blend humor with subtle sadness, capturing her ceaseless quest for understanding in a world that remains stubbornly opaque.
