Pororo went to Tong-Tong's house to borrow a storybook, but instead he took Tong-Tong's magic sketchbook by mistake. After knowing that the sketchbook is magical, Pororo uses it to win a sled race, and catch a big fish. However, when Crong wants to go the bathroom at his home, he discovered the sketchbook and stays at home. He draws a shark on the same page Pororo draws him getting a big fish, and a gigantic watermelon. Luckily, Tong-Tong comes to save them from the shark.
