is one piece episode 582 filler?

As Nami, Sanji, Chopper, and Franky look over the head as Nami notices how his head is similar to Buggy, which she attributed to as being weird. She asks if he knows where they are.

The head becomes indignant, saying that Nami should behave like a proper lady. Nami picks him up by the cheek, saying he should be nicer to the people who put him back together.

The head says he will sympathize with her, seeing as she has been stripped of all she had. Nami tells him that she has not been stripped and is wearing fashionable clothing.
