is one piece episode 46 filler?

As the crew sail towards Loguetown, Nami wonders about Buggy's whereabouts. After being launched into the air by Luffy, he is sent to an uninhabited island with many of his body parts still missing.

He escapes on a raft to a second island, where he is captured by an aggressive bird. The bird attempts to eat Buggy, but spits him out into the sky.

Buggy is sent to a third island, this time the Island of Rare Animals, where he is confronted by Gaimon. After discovering Buggy is not a poacher targetting the animals, Gaimon befriends him, drinking by a campfire.
