The third set of levels in this game is called "Tuning the Toms" and the 5th level begins with Quat saying "There's no obstacle that will stop me from achieving my goals. No challenge that I will not meet head-on." In this 5th level you will need to maneuver Quat around a box at the start and then over a small gap. After you move over the gap press right twice and he will fall into a second gap that's hard to see and make a comment saying "Not fair! How was I even supposed to see that?" This will earn you the achievement.
