is one piece episode 626 filler?

The Thousand Sunny is still in the water as a massive sea creature arises from the waters, carrying Breed. As the rest of the ship's residents sleep, Usopp, Franky, and Chopper keep on the lookout for Doflamingo, when all of a sudden, Breed and his army of Sea Lapahns attack the Thousand Sunny and everyone on board.

In response, the Straw Hats and everyone else begin fighting off the Sea Laphans when Breed suddenly calls off the attack, revealing himself atop the Thousand Sunny.
