Fighting Tongue Slash

After focusing Senjutsu chakra to his snaking tongue, Fukasaku then will strike it towards his opponent. Because of the natural energy-augmented chakra built up in his tongue, it will become super-fast and sharp. The tongue can then easily cut through most foes.

In the anime, Fukasaku instead produces a highly pressurized stream of water from his mouth capable of even slicing through metal like Sasori's Water Stream Shooters that can cut through rocks.
