is one piece episode 898 filler?

Luffy and Zoro encounters Basil Hawkins, who had become one of Kaidou's officers. They begin fighting, with Luffy now armed with a katana.

Luffy and Zoro decimate Hawkins' troops. A giant lizard attacks Luffy.

Luffy takes the animal lizard and throws it at Hawkins, who impales the animal with a straw sword. Zoro attacks Hawkins with a flying slash, but one of Hawkins' subordinates mysteriously ends up getting slashed instead of him.

Hawkins explains his Devil Fruit power; he has straw dolls hidden inside his body which each represent one of his soldiers.
