is one piece episode 83 filler?

Luffy continues his journey to where the mountain is, but he is intercepted by Wapol and his men. He decides to ignore the king but is attacked by his two subordinates.

The lapahn he saved before and its group come to the rescue when they try to attack Luffy. They held back Wapol so Luffy could get away.

Once he reaches the mountain, Luffy starts climbing it. Vivi rescues Usopp after both were swallowed by the avalanche.

They start walking until they encounter Zoro, who was buried in snow. In the mountains, all the lapahns have been defeated by Wapol and his two followers.
