All cored by ABC's Zaire Sara Haines. Reporter: They're multi. Million tie cons, Kevin o'leary, and Robert Herr Ja vehicle. The risk-taking rivals are diving into uncharted waters in "Gma's" shark versus shark showdown. Greetings, sharks, yes, I'm talking to you. Challenging you to a competition. Please report to receive your orders and may the best shark win. Back to times square. There's business. Take Kevin down. Reporter: Facing off for the greatest business challenge ever. Welcome, your task is to man a New York City food truck. And the person to make the most money will go on to the finals. You have 30 minutes to sell. Robert, you are manning the pizza truck, Kevin, you have the grilled cheese. Giving you each $100. Five items that'll help boost your chances for a victory. Get my guitar, 60 cup takes, okay? I want dogs, balloons and clowns. I want the balloons on the clowns and the dogs. Let's go. Reporter: First, a brainstorming pow wow with business partners. Win this thing. Reporter: Kevin's strategy, offer a free cupcake in a jar with each purchase. Limiting the menu to three sandwiches to build up inventory, and live music to generate buzz to increase traffic. If you buy two slices, you get a free cookie or a free drink. Reporter: Robert's game plan, pricing competitively to drive traffic. Increasing sales by offering a free drink or cookie with every two slices purchased, and clowns and puppies. We're going to sell pizza. Reporter: The competition begins now. Let's go! Who wants lunch. Hey, guys. Are you hungry? Grilled cheese, guys. Come here, let's talk. Selling pizza right next door. 10 bucks, lunch to go and a free cupcake in a jar. I'll do it. Grimed cheese. Don't eat the grilled cheese, you'll be sorry later. The sharks fight tooth and nail to win. Doing just about anything to make the biggest catch. Somebody get the clown arrested. That's brilliant. I know. Oh, my gosh, he's carrying a customer. Ladies, forget the pizza. Three minutes. Over at this truck. Round of applause. Reporter: Are you guys pulling your weight? 30 seconds. Go, go, follow the clown. Thank you. This is awesome. Thank you. Reporter: Three, two, one! The competition is over. But in the end, only one shark can rise to the top. The Numbers are in.
