Kugelmugel appears as a young man with violet eyes and white hair kept in two long pigtails. He wears a red beret, from under which springs an ahoge. Kugelmugel wears a white vest with a blue-striped dress shirt underneath. He also sports baggy purple shorts, tan leggings, boots, and a small bow. On both his vest and beret is an insignia resembling a coat of arms.
He and Ladonia are equal in height to one another, and shorter than Sealand. Liechtenstein appears to have mistaken him for a young girl, though the other countries have not made this mistake.
