The Third Kazekage (episode)

is episode 24 of the Naruto: Shippūden anime.

Synopsis
Sasori attacks with an Iron Sand pyramid and prism, but Sakura is able to fend them off, causing a cave in in the lair. Sasori then uses the Iron Sand to create a makeshift globe-model out of randomly growing spikes of iron, one of which hits Sakura and paralyzes her with poison. With a one last attack from the Third Kazekage puppet, Sasori attempts to kill the seemingly helpless Sakura, only to discover that Sakura is somehow immune to his poison and she destroys the Third Kazekage puppet with a single punch.
