"Predator!!" (捕食者!!, Hoshokusha!!) is chapter 47 of the original Naruto manga.
Still separated from Team 7, Naruto is attacked and swallowed by a giant snake. To escape, he creates a number of shadow clones, bursting the snake from the inside. Meanwhile his teammates are taunted by the enemy ninja who has the scroll that Team 7 needs to pass the second phase of the Chunin Exam. He consumes the scroll, forcing Sasuke and Sakura fight him if they want it. Sensing how dangerous the ninja is, the two try to flee but are easily followed. As the ninja and his snake allies begin to attack, Naruto appears and draws the ninja's attention.
