is one piece episode 75 filler?

Mr. 3 decides to fight Luffy, because he suspects that Mr. 5 and Miss Valentine are not strong enough. So he orders them to defeat Usopp and Karoo.

Mr. 3 blocks Luffy's feet with his wax, but the young pirate uses it to destroy a portion of the construction that is killing Zoro, Nami and Vivi. While doing this, the wax around his feet breaks, but the transformation of his friends in statues accelerates.

Luffy tries again to destroy the Giant Candle Service Set, but Mr. 3 defends his creation with some Candle Walls.
