"Three Minutes Between Life and Death" (生と死の三分間, Sei to Shi no Sanpunkan) is episode 25 of the Naruto: Shippūden anime.
Sakura reveals to Sasori that she brought an antidote to his poison. Meanwhile, Deidara attempts to split up Naruto and Kakashi by creating a swarm of explosive jumping crickets out of his clay and having them pursue Kakashi. Kakashi makes a shadow clone as a decoy, and the crickets, mistaking the clone for the real Kakashi, detonate harmlessly. Sakura and Chiyo ready themselves for the battle with Sasori, who reveals the reason behind his eternal youth: he transformed himself into a human puppet.
