is one piece episode 154 filler?

The Straw Hats, with the help of the Speedy Crab, are finally transported to Skypiea. Robin mentions the sign Skypiea which they see and Nami indicates that it is the same name on the map which Luffy had in a destroyed ship previously.

The Straw Hat Pirates land on Skypiea and begin exploring the new environment. They comment on the fluffy cloud, the fluffy cushion, the fruit - Conasshu, the flowers, etc.

While exploring, they hear the sound of a musical instrument and Zoro comments that someone is present.
