is one piece episode 226 filler?

The Straw Hats are deceived by Foxy, who uses his Noro-Noro Beam to trap them in place and drop them into a deep pit on the deck of the Sexy Foxy. Luffy busts through one of the pit's walls, and the Straw Hats are confronted with Foxy, who has taken up an obvious disguise that Luffy nonetheless fails to see through.

Eventually Sanji sets him on the right track, and Foxy makes a getaway covered by his powers. Luffy, Nami and Usopp chase after him, while Zoro and Sanji are frozen in a compromising position.

Nami and Usopp find a door with a message that only men can enter.
