is one piece episode 322 filler?

Franky stands on Scrap Island after chasing his swim briefs through Water 7 to the Straw Hats' new ship. He demands that Luffy, who has his swim briefs currently, return it.

Although somewhat humiliated, with the people of the city yelling at him that he's a "pervert", he still stands proudly against leaving, even posing before the ship shamelessly. The townspeople cover their children's eyes, and Luffy is impressed by Franky's determination.

Nami just says Franky is a pervert, much like the townspeople were calling him.
