is one piece episode 131 filler?

The scene opens 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 onto the deck, sees the island, and gives a howl of joy. Upon landing on the island, Sanji notices that it is 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.
