Create a full-length photorealistic image of an elephant resembling the framework of a mouse, maintaining its head intact, showcasing its distinctive facial features. The skin should exhibit the textured appearance of an elephant while incorporating soft fur elements reminiscent of a mouse. Design the background inspired by the habitats of both animals, blending lush savannah elements with cozy, grassy nooks typical of a mouse's environment. Ensure the scene captures a whimsical yet realistic portrayal, emphasizing the unique combination of these two creatures.
