is one piece episode 350 filler?

Having stolen Luffy's shadow, Moria now has the means to give a new life to Oars to the horrors of Nami, Usopp and Chopper. Perona begins to be suspicious of Kumacy thinking he's talking.

The three Straw Hats begin to make funny noises in the bear zombie. Hogback tells of how he has preserved the No. 900 zombie and the three henchpeople of Moria begin to think of their dreams.

It wouldn't be very long for Moria to build an empire of zombies. In the freezer, Oars lays while Gyoro, Nin, and Bao head to get him.
