is one piece episode 556 filler?

The fight has started. Luffy charges towards the enemies and punches them.

Sanji and Zoro treat it as a competition between them, wanting to see who can defeat the most number of enemies, confusing Jinbe. A fish-man tries to attack Jinbe but is stopped by Robin, who comments that Jinbe should just ignore them as this is their normal behavior and Nami says that they have not changed one bit.

Franky hops onto the Thousand Sunny and comments that everyone is getting warmed up. Franky announces that it is time for them, prompting Usopp and Chopper to ask about the new weapons excitedly.
