Create a photo-realistic image of the men's freestyle swimming finals at the Olympics. The scene captures an intense competition as swimmers from various countries battle fiercely in a freestyle crawl. In lane 4, a cute koala stands out among the athletes. The koala is wearing a colorful inflatable swim ring around its waist, equipped with a snorkel, and has an oxygen tank strapped to its back. The koala is swimming earnestly, its small limbs paddling with determination. The water splashes dynamically around the competitors, highlighting the speed and intensity of the race. The background features the Olympic pool, with vibrant banners and spectators cheering in the stands. Emphasize the contrast between the human swimmers' intense focus and the playful, endearing presence of the koala, adding a whimsical touch to the event. The image should be vivid and lively, capturing the spirit of competition and the unique charm of the koala, without including any text. --ar 1:1 --niji 6
