The heat is on as Drew and Jonathan renovate their kitchens before Brett Waterman comes to town to deliver his verdict.

Drew sets out to win with an over-the-top master suite; "Desert Flippers"' Eric and Lindsey Bennett are on hand to judge; the winner gets to play with penguins.

The brothers come out swinging to see who can design the best party-ready outdoor decks and patios; mother and daughter duo Mina and Karen from "Good Bones" come by to judge, giving the winner a chance to zip line to the beach.

Jonathan and Drew redesign their guest bedrooms and bathrooms for the judges, and the loser has to go out into the Gulf to catch shrimp and cook a meal for the winner and the judges.

Jonathan and Drew tackle the front of their houses in the final stage of their flipping competition; the public makes the final call when the houses go up on the market, and the winner with the most profit donates the proceeds to a local charity.
