Mission 7-3

 * Description: Complete 2 laps within the time limit!
 * Course: Tick-Tock Clock
 * Character: Donkey Kong
 * Time: 1 minute and 30 seconds
 * Walkthrough:

It's Tick-Tock Clock with an upgrade! The spinning gears and moving clock hands are faster and trickier to drive through, there are now three pendulums, which is a pain, so time it right, and a very fast shortcut. Hit the item boxes, because they contain three mushrooms. Boost across the four spinning gears with them carefully, then go through the next item box available and use the gear shortcut. It will take Donkey Kong further and faster down it, and if you want to get really creative, use a mushroom and get maximum speed! However, make sure you don't get on the wrong gear, because it will drastically slow down the kart. All the gears occasionally stop and switch directions, so look before you drive.

Mission 7-4

 * Description: Use shells to defeat all 30 Goombas within the time limit!
 * Course: Mario Circuit
 * Character: Toad
 * Time: 2 minutes
 * Walkthrough:

Get the green shells out of the item boxes, three if you have none, one if you have any, hit the Goombas before they get away, and that as simple as it gets. A good idea is to not only fire shells point-blank but out at the group. You may get lucky and hit the farther Goombas.
