Get over the wall before the time is up
	Fail to get up the slope before the whistle blows
	The longer you take the more slippery it gets

All the contestants must climb up this tall steep slope - half of which is a flat ramp, with the other half being curved like a halfpipe. There are ropes fixed to the top of the wall to help, but the contestants have to get most of the way up the slope to reach them.
Once up, they have to slide down the slope on the other side to make it through to the next game.
To make things harder; there are guards spraying the wall, and the contestants, with water cannons.
Super version
A giant fan blows across the bottom of the wall at hurricane strength, and two Gaurds are suspended on ropes, halfway down the wall, attempting to stop contestants from climbing up.
