Land loving contestants, including a life-long Hulkamaniac and Flash Dancer, will face the Rumble Bridge and Trampoline Sweeper. In addition, courageous competitors will have to dodge cannonballs and squid chum raining down from the swashbuckling themed Circle Challenge on this week's episode of "Wipeout," featuring the world's largest obstacle course.
