Create a vibrant and playful image of a sumo wrestler monkey. The design should be unique and colorful, maintaining key characteristics of a monkey, such as expressive eyes and distinctive facial features. The sumo elements should include traditional sumo attire like a mawashi (belt) and a topknot hairstyle. Incorporate elements that emphasize the strength and size typical of a sumo wrestler, and include a dynamic pose to highlight the monkey's readiness for a match. The overall look should be fun and whimsical, making it a truly one-of-a-kind depiction of a sumo wrestler monkey."
