Super Mario Kart/Hazards

Pipes
If you hit a pipe head-on you will come to a complete stop so try to avoid them at all costs. If you just clip the side of a pipe it will slow you down but not stop you completely. Pipes can be found on Mario Circuit, Donut Plains and Vanilla Lake courses.

Gravel
Gravel patches are usually found on the outside edge of a bend. If you drive over one you will lose grip on the track and you will also be slowed down. These gravel patches are found on most types of course.

Deep Water
Deep water can be identified easily as it is dark blue, as opposed to the light blue water that you can drive through. If you fall into deep water, you will have to be fished out by Lakitu, the track marshall, and he will place you back on track. You will lose quite a lot of time if this happens and Lakitu will also take 2 coins from you as a penalty. Deep water can be found on Donut Plains, Koopa Beach and Vanilla Lake courses.

Cheep Cheeps
These bouncing fish are only found on Koopa Beach courses. If you drive into one your kart will spin out, just like when you hit a banana skin. They are often found near deep water to try and get you to slide into it.

Thwomps
These enemies rise and fall at certain times. When a thwomp is in the air you can drive under him, but if you time it wrong he will squash you flat. If you drive into one you come to complete stop, just like hitting a pipe. Thwomps are found only on Bowser Castle courses and on Rainbow Road.
