A hyperrealistic photograph of a tiny, smiling koala bear hanging from a high-rise office window by a harness, holding a slice of pizza. The koala is looking directly at the camera with a mischievous glint in its eyes. Inside the office, a surprised businessman is staring out the window at the unusual sight. The koala is surrounded by the bustling city skyline, with towering skyscrapers and passing cars visible through the window. The overall atmosphere is one of whimsical absurdity and the unexpected joy of the moment. --ar 1:1 --niji 6
