Episode 20 - Hiruko vs. Two Kunoichi "Hiruko vs. futari no kunoichi" (ヒルコVS二人の女忍者)

Chiyo explains to Sakura that Sasori used to be one of the best puppeteers in Sunagakure, but he began experimenting with real people. Sakura learns that Sasori's true body is hiding within his favorite puppet, Hiruko, ensuring that he cannot be attacked while controlling it. The only way to defeat Sasori is to destroy his puppet. Using teamwork, Chiyo and Sakura are able to dodge Sasori's attacks and demolish the puppet, from which Sasori himself emerges. Just outside, Deidara begins telling Naruto and Kakashi how much stronger Sasori is compared to himself.
