"Let the Wonk One In" is the fifthteenth episode of the second season (and sixty-seventh episode overall) of Randy Cunningham: 9th Grade Ninja and the third Halloween-themed episode of the show. It premiered on October 17, 2014.
Randy unleashes the terrifying orange Halloweenja suit from the Nomicon and soon discovers that it’s a force he can’t control.
- This is the third Halloween episode, the previous two being "Dawn of the Driscoll" and "Night of the Living McFizzles".
- The title is based off the 2004 Swedish vampire novel and the 2008 Swedish romantic horror film Let the Right One In.
- The Forbidden Knowledge of the Shadow Warrior in the NinjaNomicon reappears, previously appearing in "Dawn of the Driscoll".
- The part where Randy throws the NinjaNomicon and sucks the Halloweenja suit into it is reminiscent of the film Ghostbusters.
- It's revealed in this episode that McFist is creeped out by retro Halloween music.
- This is Rachel's second speaking appearance and first main appearance.
- The Halloweenja's magic circle is a reference to the Disney cartoon Gravity Falls.
- In the background, a plastic figure snowman is wearing the same hockey mask of Jason Voorhes from the "Friday the 13th" franchise.
