After focusing senjutsu chakra to her tongue it grows to its maximum limit and has been reshped with a face. The tongue will then seek out the scent of its target. When the target is she found ensnares it to prevent escape and marks it with a corrosive chemical. Shima uses this to find Pain's camouflaged Giant Chameleon, allowing Fukasaku to use War of Words Decapitation on it.
Trivia
Zessen is written with the kanji for tongue and battle. It can be translated as to battle with tongues. In normal use, however, it means war of words, or verbal dispute. Just like Fukasaku and Shima are having all the time.
