"Animal District" (アニマル番外地, Animaru Bangaichi) is episode 185 of the Naruto: Shippūden anime.
As Konoha begins its rebuilding process after Pain's assault, an ostrich named Condor tells some baby ostriches about how he once had a rival named Naruto who kept trying to prevent his freedom.
After Team 7 had caught Condor, he managed to escape and taught himself ninjutsu to protect himself. As a result, Tsunade dispatched a team consisting of Naruto, Shino, Lee, and team captain Kotetsu to retrieve him from the Zeroth Training Ground. When they spotted Condor, Shino attempted to capture him, but his bugs were all eaten by insect-eating plants. After Lee lost to a boxing kangaroo and Kotetsu and Naruto were unable to defeat Condor, the squad decided to retreat. However, they were found by Condor and his team, the Four Ninja Animal Warriors, who launched an attack against the shinobi.
As Shino dealt with the anteater that ate his insects, Lee battled the boxing kangaroo and its joey. Condor created shadow clones to battle Naruto and his clones, while Kotetsu was beaten by Condor himself. In what he perceived to be his dying moments, Kotetsu thought only of his partner, Izumo, and how they dreamt of becoming jōnin together. At that moment, Izumo, who had been upset that Tsunade had not sent him along with Kotetsu, intervened and the two used their Water Release: Starch Syrup Capturing Field in combination with the Conch Shell Mace to defeat Condor and bring him back to Konoha.
As Condor finishes telling his tale to the baby ostriches, he is spotted by Naruto, who asks him if he is trying to escape once more. Calling Naruto an idiot, Condor and the baby ostriches attempt to flee as Naruto chases after them.
After Naruto returns from his mission, Tsunade's face is seen carved on Hokage Rock, despite the fact that it was not added until after Naruto left the village with Jiraiya. In fact, when Naruto returned after nearly three years, he remarked that the only thing different about the village was that Tsunade's face was now on the monument.
When Shino's kikaichū are eaten, he appears distressed, even though they only live for a few hours. After being eaten by a Venus fly trap, it is revealed that Shino had named each one, despite their short lifespan.
