"The Search for Members!!" (メンバー探し!!, Menbā Sagashi!!) is chapter 283 of the original Naruto manga.
With Team 8 unable to help him find Sasuke, Naruto approaches Shikamaru. Shikamaru cannot go on a mission since he is still helping with the Chūnin Exams, but Chōji offers to help instead. Having not seen Chōji in several years, Naruto observes that he has gained weight. Shikamaru pulls Naruto out of the way as Chōji attacks an ink lion that was sneaking up on them. They locate the intruder (Sai) and Shikamaru provides support as Naruto tries to apprehend him. Unimpressed by Naruto, Sai asks if he is perhaps a girl.
