"Granny Chiyo and Sakura" (チヨバアとサクラ, Chiyo-Baa to Sakura) is chapter 265 of the original Naruto manga.
Chiyo informs Sakura that Sasori is hiding within Hiruko, a puppet used as his armour. Sakura believes that Chiyo, as Sasori's grandmother, will have useful knowledge of Sasori's puppets, but they have been apart for too long for this to be the case. They must also be wary of the fact that Sasori's entire arsenal is likely coated with poison. Chiyo is nevertheless confident in their success. Meanwhile, Deidara informs Naruto and Kakashi that Sasori is stronger than he is and suggests they go back to help. Sasori attacks, but Sakura dodges his attacks with unusual dexterity and destroys Hiruko.
