Trama
Bailey is mad that London is hogging all the space in their cabin, so she makes up a "Sea Snark" attack, but later feels guilty and tells her the truth. Meanwhile, when Zack uses up both his and Cody's meal cards buying things for all of the girls on the ship, they go broke. To make up for it, Moseby puts them to work. Because of that, Zack thinks that Cody should win the yo-yo contest for its $1,000 prize, but Cody finds himself up against the pro, Johan Yo.
