is one piece episode 161 filler?

Satori continues his attack on Luffy, Sanji, and Usopp in the Ordeal of the Ball. Meanwhile, Usopp was attempting to recover the Little Crow before it travels deep into the forest.

He tried his new weapon which was only partially functional and he wasn't able to disconnect the rope. Sanji, seeing Luffy and Usopp became upset and comically gave both of them beatings.

Sanji told Usopp and Luffy that they need to temporarily forget about the boat and join forces in defeating Satori. Satori on hearing this, used impact to attack Sanji.
