Mario Kart Wii/Mushroom Gorge

Mushroom Gorge is the third race of the mushroom cup and the first course you can fall off edges, there's one hazard at the end of the course Goombas walk very slowly, but will make the player's spin and lose speed.

In the Grand Prix, there are five item locations on the track: the first after the start but before the turn, the second on the second set of bouncy mushrooms, the third is to the right on the third set of bouncy mushrooms, the fourth is to the left on the same as above, and the fifth is after the the fourth one as above.

Shortcuts
After the starting line you need a mushroom, start turning to the left you will notice two red bouncy mushroom. And lastly, at the end, if you have a Mushroom, use it to cut through the grass at the last turn with the Goombas. If you can snipe a Goomba with a Shell, then you could use that Mushroom if you are lucky.
