is one piece episode 69 filler?

The episode starts and Usopp is fantasizing and talking to himself about how everyone in Little Garden will welcome him. Then Zoro (who is at the lowest deck) grabs an apple from a barrel full of them, takes a bite of it and asks Usopp if he is an idiot.

Usopp responds to Zoro by yelling that he could hear what Zoro just said while kicking the bottom part of wooden where he is seated. Nami yells at both of them to keep quiet and apologizes to Vivi.

Vivi keeps explaining to Nami why there are no islands, but it is easy to hit reefs due to elevated corals (presumably on the Grand Line).
