is one piece episode 92 filler?

Puppu's ship is docked in the coast of Nanohana and his Jolly Roger is waving. His pirates are looting the place while causing a fuss.

Pell, Chaka and some men are riding horses, heading to Nanohana. Suddenly, Crocodile appears on top of a building and a woman spots him.

He catches the attention of everyone in the place and a lot of people start to call out his name, including Puppu, who recognizes him as one of the Shichibukai. Crocodile says he just came to get the head of Puppu, but the pirates tell him to not underestimate them.
