Debris appears in many shapes, although it is always small and grey coloured. It is made up of grey metal bars that appear to fit together in random shapes.
Debris does not harm the flipside racers, but is a hazard because of its potential to slow the racer down, and if there is enough debris, it can knock the flipside racer off of walls. It affects all racers, not just the main character. Therefore, the player must try to steer the main character so that he avoids debris by jumping over it with the arrow key.
