Works in Nano Banana Pro, but it will work in regular, Gemini (Imagen) and ChatGPT too.

Full-body hyperrealistic reimagining of SpongeBob as the dominant, central subject of the frame. The character must occupy most of the image, shown large and clearly in the foreground, with extreme micro-detail across all surfaces. Reinterpret the character's form using real-world materials implied by their cartoon design. If the character is organic, translate them into believable biology: realistic skin, pores, micro-textures, asymmetry, fine imperfections, subtle vascularity, natural surface irregularities. If they are made of sponge, rubber, fur, plastic, metal or fabric - recreate those materials with authentic physical properties: uneven density, frayed edges, dents, worn spots, micro-scratches, dust buildup, discoloration, soft dirt, natural material aging. Preserve the character's iconic silhouette, proportions, colors and overall identity exactly, but render every surface as real physical matter with maximum clarity and tactile realism. Place the character in their iconic environment, but treat it strictly as background: soft-focus, gently blurred, atmospheric, and non-distracting - a realistic version of the world where the audience typically sees them. The background should only provide context, never compete with the character. Lighting is realistic and cinematic, with grounded contact shadows, natural reflections and depth. No cartoon shading, no stylization - fully real-world interpretation. 8K clarity, extreme micro-detail, crisp edges. -ar 2:3
