The fearless competitor continues the battle to win extraordinary food challenges across the country. This season, Webb will attempt the unthinkable by taking on edible encounters that would make most people run and hide—including a fire and ice challenge—with scorching hot popcorn measuring over 1 million Scoville units (the scale that measures a pepper's heat) and a 64-ounce frozen hot chocolate near Louisville, Kentucky. Webb also takes on a 29-inch New York-style pizza in St. Louis, that's so big he can't tackle it alone; and in Nashville, Tennessee, he goes for the signature spicy delight, "hot chicken," with tenders slathered in a concentrated hot sauce made with Carolina reapers, scorpion peppers and ghost peppers.
