Harry, Ron, and Hermione are unable to find a way to survive underwater for the second task, leaving Harry panic-stricken. He is rescued on the morning of the task by Dobby, who gives him some Gillyweed that he heard Moody and Professor Sprout talking about. The Gillyweed gives Harry flippers and gills and allows him to find Ron at the bottom of the lake. However, he refuses to leave the hostages belonging to the other champions behind, and insists on rescuing Fleur's sister when Fleur does not arrive. Although Harry finishes last, the judges (apart from Karkaroff) still award him high marks for 'moral fibre.'
