is one piece episode 153 filler?

The Knock Up Stream drives the Going Merry through the Emperonimbus Clouds. Luffy finds it to behave just like water and does his best to hold his breath.

Soon the ship breaks the upper surface of the White Sea and its wings break off. Back in the Blue Sea, Cricket sits on the island as the Knock Up Stream dissipates, lost in thought.

Floating with his crew on the remains of their raft, Teach is impressed that the Straw Hat Pirates got away. Burgess is angry that they lost out on a possible bounty, but Teach reasons that they will cross paths again if they remain on the Grand Line.
