Diddy Kong Racing [8] - Unlock The Clock

We step outside of Adventure mode and into the Track list to unlock T.T. This clock has the fastest acceleration, fastest top speed by a landslide (especially in the car, where he gets an added boost on zippers), and handling smack dab in the middle between Timber and Bumper. A certain time must be achieved in Time Trial to make T.T.'s ghost appear, and then you must beat his ghost on every track to unlock him. It is very challenging if you do not take advantage of the zippers. If you let go of the gas for the entirety of each zipper, it is ridiculously easy. You can also tap "A" 4 times per second to drive faster than you would just holding the button.
