More kids join this new ninja group and scare away the vagrants from the area, forcing them to relocate from SodoSopa to Shi Tpa Town and the Whole Foods Market, including Barbrady, who has been evicted from his home.
The news reports that the kids playing as ninjas are actually joining Islamic State of Iraq and the Levant (ISIS) due to the similarity of their clothing, and they are blamed for the increased homeless problem in South Park.
IGN's Max Nicholson gave the episode an 8.0 out of 10, noting: "This week's South Park was out for blood on its former self, as the townspeople shunned Officer Barbrady... the only thing that didn't land was the police brutality subplot".
[1] Chris Longo from Den of Geek gave the episode 3.5 out of 5 stars and summarized in his review: "it's shaping up to be one of the best seasons in a decade if it can stick the landing".
Club, Dan Caffrey rated the episode an A− and noted that "As it turns out, 'Naughty Ninjas' has less to do with institutionalized racism (not in a direct sense anyway) and more to do with people only being compassionate when it suits them.
