What I Can Do…!! (出来ること…!!, Dekiru Koto…!!) is chapter 269 of the Naruto manga.
Chiyo protects herself and Sakura from the Third Kazekage's puppet's Iron Sand with a shield installed in her arm. The Iron Sand nullifies the arm afterwards. Although Chiyo is now handicapped, Sakura realises that Sasori, a puppeteer, can only be defeated by Chiyo, another puppeteer. Since normal puppets can easily be defeated by the Iron Sand, Sakura offers herself as Chiyo's puppet. This increased agility, combined with Sakura's superhuman strength, allows them to counter the Third's attacks.
