Three Minutes Between Life and Death

is episode 25 of the Naruto: Shippūden anime.

Synopsis
Sakura revealed to Sasori that she had taken an antidote to his poison which she had brought with her. Meanwhile, Deidara attempted to split up Naruto and Kakashi by creating a swarm of explosive jumping crickets out of his clay and having them pursue Kakashi. Kakashi made a shadow clone as a decoy, and the crickets, mistaking the clone for the real Kakashi, detonated harmlessly. Kakashi then caught back up with Naruto and formulated a plan. Sakura and Chiyo readied themselves for the battle with Sasori, who revealed the reason behind his eternal youth: he had transformed himself into a human puppet.
