is one piece episode 93 filler?

As the Straw Hats arrive at Arabasta, Nami expects everyone to be on their best behavior. However, Luffy immediately runs off to get food, separating from his crew.

The crew then notices that Mr. 3's ship is docked nearby and Vivi remembers that the ship moves by the means of Mr. 3's Doru Doru no Mi. Vivi says that she and Karoo cannot go onto the streets since most of the citizens would immediately recognize her, so Usopp comes up with an idea to walk through the streets while hiding under a blanket.
