After Team Avatar crash-landed in the Foggy Swamp in 100 AG, Sokka emerged from the water and was alerted by Katara that an elbow leech had attached itself to his elbow, a remark to which Sokka frantically reacted by asking her where it was. He pulled it off with great effort and tossed it away. In 174 AG, Toph pulled an elbow leech off Korra. It became attached to her as she was lying in a shallow pool of swamp water, though she had failed to notice it.
