is one piece episode 574 filler?

The Straw Hats are heading to the New World. Nami is taking a bath in the Thousand Sunny and Chopper comes in.

Nami asks Chopper if he wants to join her in the bath and he says no claiming that he took one two days ago and the cloud reminds him of cotton candy. Sanji and Brook walk by and saw Nami taking a bath so they stare at her.

Nami asked Chopper to move aside away from the cloud she made and the cloud electrified Sanji and Brook. Chopper claims he is scared and he won't eat the cloud.
