Showdown: Gaara vs. Kimimaro

is episode 126 of the original Naruto anime.

Synopsis
Lee, not wanting help, tries to bypass Gaara and attack Kimimaro. Because Lee is still recovering from his operation, Gaara forces him to sit. Using his sand, Gaara tries to crush Kimimaro, though by activating his cursed seal Kimimaro survives the attack. Calling upon a greater amount of sand, Gaara tries to bury Kimimaro, though advancing his cursed seal to level 2 allows Kimimaro to survive and escape this as well.
