Hidden Bonus Tokens
You can collect red with white lightning (worth 100 points), red with yellow lightning (worth 500 points), and gold bonus tokens (worth 2,000 points) throughout each chapter of Story mode. You can use your bonus points to unlock new characters, concept art and movies. In Chapter 3, you must navigate through an orchard until you find a broken cart that you may use to jump the orchard's fence. After you jump the fence, you will find a trail of tokens that leads to a postcard. In Chapter 4 of Story mode, a large waterfall with a cliff becomes accessible. Jump onto the cliff to discover another trail of bonus tokens. According to Neoseeker.com, you can also earn bonus points by competing in mini-games to achieve new high scores and take shortcuts to win chapter races.
Shortcuts
You can take shortcuts to win chapter races and also earn bonus points in Story mode. A shortcut is available in the second race of Chapter 1. After passing the firehouse curve, take the dirt road on the right side of the racetrack. This dirt road helps you avoid spinning out due to the sharp curve, giving you the opportunity to get ahead of the racers who lost control. In Chapter 2, you can take a shortcut to find the postcard required to unlock Ornament Valley. A fence around the drive-in theater blocks you from accessing the pit. Drive up the dirt ramp beside the drive-in theater to discover a dirt path blocked by a large boulder. According to Neoseeker.com, you can jump over this boulder using your car's boost-jump acceleration. This shortcut takes you to the remaining postcards required to unlock Chapter 3.
