K, Here's how to get a lap (not a race: my best race is 41.91) of 5.53 seconds (or thereabouts) in Frappe Snowland:
First, i used Yoshi as my driver, as lightweights go faster. Also, the lap tmes will look something like this (so lap 3 is the 5.53):
L1: 22:00 or so
L2: 14:00 or so
L3: 5:53-6:50 maybe faster....
To start, turn around right at the start. (hold a and b then turn) go to the right side of the track (from your view when you turn around) then drive to the middle of the bridge. Come to a full stop, then turn using the a and b slide so your driver is facing the corner where the the right side of the road, the snow area, the bridge, and the river meet. drive right at this corner, and make sure you hop it so you land on the snow part. (you may sink into the river the first few times you do it) then, drive, while still in the snow, across the finish line, then hit a hard right so your driver has to be carried back on track by Latiku. you should be realinged behind the goal, about where the end of the bridge and the road meet. Then, turn around (again) to the middle of the bridge on the right side, then do the exact same thing. (hopping the corner). When you cross the finish line, you should be credited with a lap. (not a 5.53 second lap, more like a 22-25 second lap.) Then hit a hard right again, and get carried back on the track again. repeat until you get to the part where you are on the snow the 3rd time. now the hard part. Time it so you are carried by Latiku and you cross the finish line at the same time. you should be credited with Lap 2. Now, when you get placed back, use a mushroom IMMEDIATLY when your character can get back moving, and drive straight at the finish line. If done correctly, you will be credited with a 3rd lap, which will be at a time of about 6 seconds, and possibly as fast as 5 and a half seconds!!!! (my best is 5.53) Your total time should be about 45 seconds (my best is 41.91, but it is rumored that you can get times of 28 seconds or less, I don't know how though.)
If that was hard to understand, sorry, but it is hard to explain. If that doesn't work, I will try to explain again (better). It may take some practice to do it right, but when you do, your friends will stare at you in awe! (or think you hacked into the game, depending on your friends)
