is one piece episode 108 filler?

Chaka orders the royal guards to attack the rebels in order to protect Arabasta. Meanwhile, Koza and the rebels head to Alubarna.

The Straw Hat Pirates are still locked up in Crocodile's cell. Crocodile taunts the tied up Vivi, with a key to get the locked up pirates.

Vivi is able to get free from the ropes but the key that Crocodile had "accidentally" slips from his hands and goes through his trap door where one of his many banana crocodiles eats it. "Mr. 0" gives everyone in his VIP room one hour to live due to water filling the room.
