Bart Simpson, trippy, psychedelic colors, messy spiky hair, green t-shirt, blue shorts, sneakers, sitting on a colorful swirl-patterned couch, in a dreamy room with distorted walls and floors, surrounded by vibrant flowers, paisley patterns, and abstract shapes, with a huge smile on his face, eyes closed in ecstasy, hands holding a psychedelic-colored donut, warm soft lighting, blurry background, whimsical atmosphere.
