is one piece episode 353 filler?

Robin, Franky, Usopp, and Chopper rush across the stone bridge back towards the Thousand Sunny. They'd been told by Brook they would locate their missing crewmates Luffy, Zoro, and Sanji aboard for safekeeping.

Franky asks Usopp about Oars, whom Usopp had been seen being brought to life after being implanted with Luffy's shadow by Gecko Moria. They return to the Sunny to find the zombies had ransacked the ship in the process of returning their victims.

Usopp finds the missing crewmates in the dining room in assorted humiliating poses.
