Aang traveled to Kyoshi Island, accompanied by Katara and Sokka, with the intent of riding on an elephant koi for recreation. After spotting a group of elephant koi jump out of the water in the nearby bay, he ran out into the water and latched himself onto the dorsal fin of one of the fish as it swam across the surface of the water. After a while, the koi fish disappeared, as their natural predator, the unagi, approached, leaving Aang stranded in the bay. Following the end of the Hundred Year War, Aang returned to Kyoshi Island with his son, Tenzin, to ride the elephant koi once more.
