Remember those spinning hammer things connected by a bar? Remember how sometimes they all show up on top of each other and they are in a formation that look kinda like a staircase? Like this?That's when you do the rail slide.

As you are getting closer to the "Staircase" look at the middle of the top "Hammer fan". Keep it in line with your sight. Get in a position where, right when your sight lines up with the hammer, you will be close to the end of one of the hammer fans, or, in this case, "steps", but not too close. As soon as you sight lines up with the fan and it is at eye level, go forward and left if it is clockwise, forward and right if counter-clockwise. Remember, stay above the tips of each of the fans. They are your "steps".

If done correctly, you will not only get a kiss from each fan, but stay in line of the map's course, and have momentum going for the next obstacle. And if you are risky and stay close to the center, you might get a few hugs out of all the fans.

If done incorrectly, it could possibly use your own momentum against you, throwing you away from the course. You could miss out on kisses or even hugs, or get killed if you are too risky.

Honestly, it took MUCH more time to develop, study, practice, and get screenshots of the tactic than actually writing the guide. But yea, I hope it was useful, and if you want more tactics, I've got no life, so I can probably carry it through, even though I'm working on a guide series for another game. See ya!
