Christmas Gremlin and Alien Mug

Illustration of a whimsical holiday scene where a cartoon gremlin, dressed in a Santa Claus outfit, is joyfully riding a sleigh. The gremlin has green skin, mischievous eyes, and is wearing a red hat with a fluffy white trim. The sleigh, ornately decorated with festive patterns, is being pulled by an alien that resembles the classic grey alien archetype, with large black eyes and a small body. The alien is playfully adorned with reindeer antlers and a red nose, mimicking Rudolph. The background is a wintry night sky filled with stars and a glowing full moon, and the ground is covered with a blanket of snow. The scene captures the fun and fantastical element of holiday stories.
