is one piece episode 805 filler?

Luffy and Cracker face off, and Cracker summons more Biscuit Soldiers to attack as Luffy has Nami go back to the homies she has under control. A hungry Luffy tries eating one of the soldiers, but cannot bite into it.

Cracker proclaims that his biscuits are especially hard and cannot be eaten, but this exchange causes Nami to remember that Cracker's soldiers are made of biscuit. She then unleashes Rain Spark, dousing all of Cracker's creations with rain.

One of them strikes Luffy and blows him back, but its sword shatters, and Luffy is able to break them with a simple Gatling attack.
