A cute, chubby Santa Claus character standing in snowy winter scenery at night, wearing a full rainbow-colored furry outfit that glows with vibrant neon light. Santa has a fluffy rainbow hat with a pom-pom, a thick white beard, rosy cheeks, and bright blue eyes, holding a shiny wrapped Christmas gift with a golden bow. Snow glows beneath him, with soft light reflections and sparkles. Surrounding Santa are colorful Christmas trees covered in snow, decorated with glowing rainbow lights, and many brightly wrapped presents with gold ribbons. The background shows a magical sky filled with stars, snowflakes, bokeh lights, and a dreamy festive atmosphere.
