is one piece episode 187 filler?

As Enel watches the destruction, Usopp urges everyone to hurry before everything gets destroyed, and Luffy vows to make Enel pay while running up the stalk. Enel notices the Shandia Village and comments that because they are originally from the Blue Sea, they may "enjoy" his plan to destroy Skypiea, sending it back down to the Blue Sea.

He then directs the lightning to specifically destroy the village. The Shandia watch in horror from the boat and remark they could have been destroyed along with their village had they not evacuated as fast as they did.
