Sun and Moon

A yellow, mouse-like creature with long ears and a lightning bolt-shaped tail stands on a platform, raising its paws in a cheerful pose as a character in a red hat and white shirt holds it in a bright, glowing environment, then the scene shifts to a dark, futuristic arena where the creature is seen in a battle with a red-clad fighter, the words "GAME SET" appear in large green letters as the creature is shown in a fighting stance, followed by a character in a Santa hat striking a pose with a glowing fist, all set against a backdrop of a dark sky with a large blue planet and a city silhouette.
