is one piece episode 211 filler?

For the Straw Hat's next event, they must win a game of Groggy Ring to get Chopper back. Sanji and Zoro must work together to defeat the Groggy Monsters.

The referee introduces the two teams, Sanji and Zoro as the two guys who sabotaged the Foxy Pirate's teams in the first event, and introduced the Groggy Monsters as their most powerful Groggy Ring squad. The Groggy Monsters are three giants named Hamburg, Pickles, and Big Pan.

After introducing Zoro as the 60,000,000 belly man, Pickles says he was wondering what kind of opponents warranted them coming out and playing.
