A charming cartoon illustration depicting a turquoise-colored shark joyfully surfing on a sun-drenched summer day. The shark, with endearing pink blush and pink-framed sunglasses, beams with excitement, surrounded by sparkly effects as it rides a golden surfboard adorned with crisp white stripes. The background is a playful expanse of white scattered with turquoise stars, cheerful orange suns, vibrant pink and turquoise shells, and scattered yellow pineapples, all contributing to the vacation vibe. At the bottom of the image, the text "fin-tastic SUMMER" appears, with "fin-tastic" in elegant black cursive and "SUMMER" prominently displayed in larger turquoise lettering.
