Episode 1 - "Who the hell recommended Glowing Heart"
Roulette Wheel at first thinks the challenge easy, but as he soon realizes that he can't affect his four balloons due to his lack of arms, he quickly looks for assistance. Assistance does not come with Organic Fruit & Grain Bar or OSO Novel, however, and so Roulette Wheel soon turns fatalistic. Nail Clippers, who he spotted, too proves useless and even deadly, though he manages to achieve safety after White Dango chomps his balloons.
Episode 2 - "Your Opinion is Invalid"
Later on, during the challenge, Roulette Wheel pairs up with Retainer. The two do not fall over, making them safe from elimination.
