A digitally rendered, adorable baby penguin standing on snow, wearing a bright red scarf. The penguin’s white belly glows with magical star-like sparkles. In the softly blurred background, a Christmas tree adorned with warm yellow lights adds a festive glow. The environment is snowy with a dreamy twilight ambiance, and snowflakes gently fall around the penguin. The atmosphere is whimsical, cozy, and joyful — perfect for a holiday-themed mobile wallpaper. Render in ultra-realistic cartoon style, soft lighting, crisp details, vertical orientation.
