- "...he was having enough difficulty seeing the one Bludger with which they were practicing; a minute into the practice it almost unseated him and he had to use the Sloth Grip Roll to avoid it."
In 1995, Quidditch Captain Angelina Johnson taught the Gryffindor Quidditch team this move. Harry Potter mastered it quickly and used it during a practice to avoid a Bludger. He hoped that Angelina would be impressed by this, but the unfavourable weather conditions at the time made it so that hardly anyone could see what any of the other players were doing.
