is one piece episode 679 filler?

At the arena, Sabo and Rebecca fall down to the pit with Koala arriving next to them. The slaves once turned into toys pledge loyalty to Usopp and vow to destroy the factory.

Having fallen down from the colosseum, Jesus Burgess is annoyed that Sabo ate the fruit meant for his crew, and Diamante worries over the loss of the fruit. While these two are grumbling, they are confronted by the freed toys from the basement, full of hatred for the Donquixote Pirates.

Meanwhile, Koala, Sabo and Rebecca regroup with Hack.
