After their adventures in Arabasta, the crew come upon another deserted island and split up tasks amongst themselves. Chopper is left in charge of guarding the ship, and he reminisces about the day he first made the rumble ball and his first patient, Dr. Kureha, while spending some time with the newest crewmember: Nico Robin.
The scene opening on an early dawn, where all of the Straw Hat Pirates are asleep. Nami, who is above deck, wakes up and discovers an island in the distance. She calls out to the others, and after a humorous fight between Zoro and Sanji, Luffy awakens and climbs up deck, sees the island, and gives a howl of joy.
When they land on the island, Sanji notices that it's abundant with fruit. He suggests that they gather fruit as surplus, therefore Nami has the remaining crew draw straws to see who gets to stay behind and watch the Going Merry. Luffy takes three, thinking that would make him smarter (which it didn't), and in the end, Chopper ended up drawing the longest straw, so he got to stay behind. And so, Luffy, Zoro, and Usopp go to gather fruit, Nami goes to survey the island and draw a map of it, and Sanji follows her, swooning.
