Chiyo explains that's not Sasori's real form - it's a puppet. His real body is inside. Puppet masters are poor at close range fighting and can leave openings when they control the puppet. This way the puppet becomes the armor as wells as weapon. When Sasori was in Sand, he was regarded as a genius, but he was interested in transforming humans into puppets. The current puppet Hiruko was a Sand shinobi. Puppets that maintain their original forms are called human puppets. Hiruko is a battle type puppet. They must separate it from Sasori first in order to defeat him. Although Chiyo knows how Hiruko works, its form is now different. It did not have a large shell on the back and the weapon on the left arm. Sakura has Tsunade's strength to destroy it. Chiyo tells Sakura to get close to him and break his puppet with strength, but they must dodge all his attacks because of the poison. But Sakura knows she does not stand a chance since she doesn't have the battle experience and or know about how puppets move. Chiyo lets down her hair, getting ready to fight. She says Sasori’s skill does not lie in battle experience. He’s the type to hate to wait or make others wait. She whispers to Sakura their strategy and they will defeat him together. Sasori takes off his mask. Sakura and Chiyo run toward him with kuani. His shoots out senbon. The two dodge successfully.

Deidara goads Kakashi, trying to get him to help Sakura and Chiyo. Kakashi thinks Deidara wants to fight Naruto one on one but he thinks Deidara is too strong for Naruto since he was able to capture Gaara. Naruto tells Kakashi to help Sakura and leaps toward Deidara. Deidara avoids his attack and creates another exploding bird but Kakashi takes it out with a kunai.

Sakura and Chiyo avoid all the senbon shot from Sasori's mouth. Sasori's arm weapon fires wooden casings with more senbon, that shoot out in multiple directions rather than straight on. Sakura and Chiyo avoid being scratched to Sasori's surprise. Sakura runs at him and throws a kunai which is deflected by his tail. He attacks her with his tail but stops short.

Deidara says junchuuriki are usually gloomy and hate people. They have taken two other jinchuuriki in addition to Gaara and neither their friends nor villages tried to save them. He tells them Gaara died when they removed the Ichibi and soon Naruto will too.

Sakura smashes the shell on Sasori's back and destroys the puppet. Chiyo had been controlling her and the tail with chakra strings. The real Sasori leaps away.
It's been about twenty years since Chiyo has seen him.

End: Konoha's Tourism Association with Naruto and Chiyo at the dango shop. Chiyo says she mind as well try the dango before she dies and takes a bite. She makes a strange face and drops her head. Naruto thinks she died and calls for help, but she's just playing dead.

Review: Some interesting info on puppets. Hopefully more action next time.

Notes:
Hiroku is Sasori’s 18th puppet. With the addition of Sakura and Chiyo, he will have 300 puppets in his collection of art. (he must have a big house with lots of storage!)
To make a human puppet, Sasori tears out the organs, washes it clean, drains all the blood, make sure the body won't decay, then he adds weapons and traps.
Deidara says Sasori is stronger than him.

Thoughts:
Why would a village allow a junchuuriki to be taken? That's allowing someone else to have a ultimate weapon.
