is one piece episode 368 filler?

Nami beats the two squirrel zombies into telling her what they did with the Straw Hats' treasure. She goes looking for Perona and heads to the Thousand Sunny when she spots the fallen Oars.

But Oars remains stuck to the ground since his horns are now imbedded into the ground. Using this to their advantage the Straw Hats' start beating him up, much to Oars' fury.

Oars gets back on his feet, much to everyone's chagrin and Usopp, Chopper, and Franky blame Robin for not doing "Tactics 15" properly. The former three decides to do it again anyway and using Sanji's kick, aim to attack again.
