The Challenge (1998) : 12x6

The cast members decide to spice things up and have a costume extravaganza. Tonya lets loose and Johanna realizes that this challenge shouldn't come between her and Wes. They apologize to one another and Johanna tells him there will be no second chances. At the challenge it is a battle of oats as each team must sprint to a tub full of rolled oats, collect as many as possible, sprint over to another bucket, and drop off what they have collected in a matter of two minutes. The teams soon learn that the oats are just like quick sand and this won't be half as easy as expected.
