Kevin O'Leary takes a dare from his fellow Sharks and bites into a veterinarian's product that claims to prevent cancer in pets. Later on, the Sharks enter a huge sphere to experience first-hand the entrepreneurs' virtual arcade; and four of the five Sharks hope to talk Barbara out of making what they think is a bad deal. Other business pitches include an outspoken designer from Houston, Texas who challenges the Sharks to invest in her line of fashionable clothing for women.

Things get heated when the sharks ask a husband-and-wife team to clarify the actual value of a child-care business; a chef's salad dressing mix is removed from store shelves because of offensive packaging; a golf ball cleaner.
