"Puppet Master vs. Puppet Master!!" (傀儡師VS傀儡師!!, Kugutsushi Bāsasu Kugutsushi!!, Viz: Puppet Masters!!) is chapter 268 of the original Naruto manga.
The Mother and Father puppets were created by Sasori to look like and serve the function of his own parents, they having died when he was young. Since they were only puppets, the could not give him love and he lost interest in them, leaving them in Chiyo's possession. Chiyo fights the Third Kazekage puppet with them and they are able to overpower it in a normal fight. The Third, having once been human, retains all of the abilities it had in life, including the Iron Sand. Sasori neutralises the puppets with the Iron Sand and attacks Chiyo and Sakura with it.
