Sly enters the vault and travels throughout it, passing all of the ancestors' challenges and exploring the history of the Cooper Clan members. He eventually arrives at his father's challenge, and after a moment reflecting on him, realizes that his father's move was one never placed in the Thievius Raccoonus; the Laser Slide, which allows Sly to slide across laser beams as if they were solid. Going through this final leg of the gauntlet, Sly arrives at a large door. He enters it. Mission complete.
