Pororo and friends are fishing in the sea. Petty and Poby caught a big fish but Pororo and Eddy caught none. Soon after, Eddy's pole shows a sign. Rolling up his fishing pole, Eddy is disappointed to find a small fish on the end. Pororo makes fun of the size of the fish. Eddy snaps at Pororo saying that Pororo didn't even catch a fish as little as his. Angry at Eddy's remark, Pororo throws his fishing pole and jumps in the sea with a net. He comes out of the water with a big fish. Eddy jumps in with a net too. And so begins the competition. But what will they do? A shark is near by watching them, drooling out of hunger....
