Mr. Fargo sets up a large canvas on the grass and begins a painting using blue paint. Fudge decides to eat all the blueberries that Peter and Jimmy picked, feeding a few to Turtle. Fudge lies on the ground, moaning and holding his stomach, covered in blue from head to foot. Nobody is really surprised to know that Fudge did such a thing, but Grandma gets him some peppermint medicine, and he slowly starts to feel better. Shortly after, Peter’s dad comes into the house and announces that he rented a boat big enough for seven people. Peter, Jimmy, Sheila, Sheila’s parents, Peter’s dad, and Grandma all get in the boat, and Peter’s dad sails it out to sea. They enjoy a relaxing lunch on the ocean, and both Peter and Jimmy refuse to wear sunscreen, claiming they don’t burn.

When the group begins sailing back toward shore, the wind picks up, causing large waves and making the boat rock. Jimmy gets sick, and he and Sheila hold onto Peter, terrified. Grandma calls out orders to Peter’s dad, who fails to get the boat under control and ends up falling into the water.
