Mario Kart DS/Level 3

Mission 3-1

 * Description: Destroy all 5 item boxes!
 * Course: Waluigi Pinball
 * Character: Wario
 * Time: 50 seconds
 * Walkthrough: Power boosting in this mission is not necessary at all. With a well-timed start boost, look at the bottom screen of your Nintendo DS and capture all of the item boxes according to the bottom screen. It's easier to use the bottom screen rather than the top screen because it provides a bird's eye view of the item boxes, making the item boxes' paths easier to predict. Once you capture an item box, release it's star to speed up Wario and give him strong brakes. Do this for all 5 item boxes. Try not to bump in to anything!

Mission 3-2

 * Description: Drive through all 5 numbered gates in order ... backwards!
 * Course: Delphino Square
 * Character: Bowser
 * Time: 50 seconds
 * Walkthrough: Power boosting in this mission is impossible since you will be driving backwards! With no possible start boost, continue down the path of the map as you usually would, but backwards. Just keep in mind that you must use instead of, and that  is really  and vice versa.

Mission 3-3

 * 'Description: Collect all 15 coins while avoiding the Chain Chomp!
 * Course: Luigi's Circuit
 * Character: Luigi
 * Time: 30 seconds
 * Walkthrough: Power boosting in this mission is nothing but trouble since it's almost impossible to stay in the path of the coins with Luigi's unfluid power boost. With a well-timed start boost, drive through the first straight line of coins. Once the path of the coins starts curving, repeatedly press and  to slow down and turn just about enough to keep up with the curve. At about the end of the curve, try to hold  and indirectly drive into the path of the last few coins with little small jolts of left turns, allowing you to save some time. This mission takes effort to get three stars on, so don't give up!

Mission 3-4

 * Description: Reach the finish [line] before Yoshi!
 * Course: Yoshi Falls
 * Character: Peach
 * Time: Indefinite
 * Walkthrough: Peach's power boost is reputable for being incredibly hard to manage, so it's best that you don't power boost unless stated here (and if you can pull it off.) With a well-timed start boost, head for the waterfall at the right of the barricaded bridge. Before the waterfall, get an item box and (if you're experienced enough) attempt a power boost to gain foot ahead Yoshi. Drive through the edge of the wide turn while power boosting. The next bridge is also blocked by barricades, so release your item obtained from the last item box accordingly (whether it is a star or triple-mushroom) and ride the waterfall to the left of the barricades. At the end of the waterfall there is a row of item boxes, drive through one of them and save the item. Drive through the last three zippers and release your item once on the straightaway to the finish line.

Mission 3-5

 * Description: Drive through all 8 numbered gates in order!
 * Course: ???
 * Character: Yoshi
 * Time: 45 seconds
 * Walkthrough: Yoshi is an average power booster, and if released during the right times, Yoshi's power boosts can be very rewarding in this mission. With a well-timed power boost, go forward to pass through the first and the fith numbered gates and into a warp pipe. Once on the platform, pass the second numbered gate and release a power boost to the right half-way through the right turn, and another power boost to the right after passing the third numbered gate. Release an immediate power boost to the right and pass into the fourth numbered gate. Drive inside the warp pipe ahead to be teleported to the front of fith numbered gate. Pass it, make a long power boost into the direction of the farthest visible numbered gate, and make another immediate power boost to the right and onto a ramp after passing the sixth numbered gate. Pass the seventh numbered gate directly ahead, and make an immediate right turn off the platform and into the eighth numbered gate below.

Mission 3-6

 * Description: Hit Monty Moles with shells 5 times!
 * Course: Moo Moo Farm
 * Character: Luigi
 * Time: 1 minute and 5 seconds
 * Walkthrough: Power boosting in this level is not needed, as you'll be spending your time on hand-eye coordination. With a lowly-powered start boost, drive into any item box and hit the breaks. If you've chosen the center item box, you will hit the center mole in the first row. If you've chosen the leftmost item box, you will hit the leftmost mole in the first row, and so on. It's best that you choose the leftmost mole since it is the closest hole to an item box. With a green shell ready, drive close to the Monty Mole's hole and wait for the mole to peak outside, which is a signal for you to prepare for him to jump up. Once the Monty Mole is airborne, it will try to go fall back in it's hole, but only before it does, release a green shell to knock it out. Slam on the reverse, accumulate a new green shell, and go back to knock the mole out again. Do this to the same mole 5 times. Poor thing :(.
