Create a realistic image of a super chubby Pikachu as if it existed in the real world. Imagine Pikachu with a plump, rounded body, giving it a slightly more cuddly and adorable appearance. The fur texture should be detailed and soft, blending elements of a small, robust rodent like a well-fed rabbit or a squirrel, maintaining its iconic yellow color and red cheeks. Its large, expressive eyes should have a lifelike shine, reflecting its playful and friendly nature. The electric sparks from its cheeks should look natural, as if it could genuinely produce electricity. The background should resemble a natural environment, such as a lush forest or a grassy meadow, with realistic lighting that enhances Pikachu's warm, inviting presence, making it appear truly part of the world.
