Animal District (アニマル番外地, Animaru Bangaichi) is episode 185 of the Naruto: Shippūden anime.
Mr. Ostrich has escaped again, so Tsunade organised a team consisting of Naruto, Shino, Lee, and team captain Kotetsu. They are sent to Zeroth Training Ground to retrieve him. When they spotted Mr. Ostrich, Shino decided to capture him, but his bugs were all eaten by insect-eating plants. Shino was struck greatly and began to call his bugs by names. Meanwhile they encountered the so called four fighting animals team. The team consisted of a kangaroo with boxing gloves, Mr. Ostrich, and an anteater. The fight began. Shino battled the anteater, Rock Lee the kangaroo (and the baby kangaroo hiding in the big ones belt), and Naruto and Kotetsu battled Mr. Ostrich, who has learned to speak and to use ninja skills. So, Mr. Ostrich created fake shadow clones, and Naruto created his shadow clones and they went into fight. Kotetsu fought Mr. Ostrich (who calls himself Condor). Kotetsu was unable to counter any of Condor's moves, and he began to have flashbacks of him and Izumo, about their dreams to become jōnin and how great team they were. When thinking his death was near Izumo intervened and they used Water Release: Starch Syrup Capturing Field in combination with Conch Shell Mace to defeat Mr. Ostrich. In the end, everyone managed to beat their opponents, and they finally managed to bring Ostrich back to his owner.
At the begining of the episode, when Naruto is leaving Konoha and looking at the Fourth Hokage's face, Tsunade's face is already carved despite it was carved during the two and a half years Naruto trained with Jiraiya.
When Shino's bugs are eaten, he appears distressed, although kikaichū only live for a few hours.
It appears that when Shino's bugs were eaten by the Venus fly trap, the kikaichū bugs have their names.
