In mercury city meltdown there are two pipes that if you take you will
almost always win a race. The first pipe has two ways to get to it. You
can go through some red glass which is hard to find or when you come to
the small bridge in the woods go left into the trees rite before the
bridge. You should fall off a small cliff onto a frozen river. Take that
river and you will find the pipe. Be careful in it, there are propels in
it. The second pipe is a short way from the first. At the first jump
after you come out of the other pipe go behind the glass ramp and slowly
behind the smaller ramp. Now tern around and go into the back of the
second ramp. But at the end of this pipe there are two trains that run
in front of you. If you make it out you should come out seconds away
from the finish line.
