This small brown rat has a huge festive spirit! Perched atop a large and jolly red and green Christmas mouse, it looks down in cheer and camaraderie. The two creatures are a perfect match: the tiny rat with its paw gracefully placed atop the mouse's head, signifies its trust and belonging. To bring out the joyous feeling of Christmas, I'd color the rat with a bright and inviting shade of orange and its fur white detailing. I'd make the Christmas mouse a regal and festive crimson, with bright and vibrant hues of greens and yellows for its festive pattern. I'd add blush to the mouse's cheeks and a glistening yellow in its eyes, to enhance the joyous expression in this holiday scene.
