is one piece episode 212 filler?

The episode begins with Itomimizu narrating that Sanji and Zoro have been defeated, but is interrupted when the two Straw Hats suddenly stand up. The remaining Straw Hat members cheer for them as Itomimizu goes on to doubt if Zoro and Sanji have any strength left.

Foxy then orders a "Monster Burger" from the Groggy Monsters, which causes the Foxy Pirates to go into a shock. The Straw Hats in the audience wonder what it could mean.

The Foxy Pirates then start to cheer as Hamburg, Pickles and Big Pan pull out weapons, claiming to grind, slice and crush Zoro and Sanji into a "monster burger".
