Teenage Mutant Ninja Turtles (2003) Season 4 Episode 8
On Halloween night, a mustachioed man visits April, expressing interest in a rather unusual item: a hideous six-armed idol. But the statue is no ordinary junkshop knickknack; it can be used to invoke a horde of imps that proceed to clean out the city and bring its spoils to their master, a criminal who calls himself The King of Thieves.
