Mordecai and Rigby set up an outdoor moving night, where they show a zombie movie that comes to life.
- Shout-Out: The entire episode is a homage to horror movies
- Zombocalypse strongly resembles Army of Darkness complete with Bruce Campbell lookalike hero, the cover art of Zombocalypse resembles Doom, the shot of the zombies reanimating in their graves looks similar to The Return Of The Living Dead, and the concept of a movie creating zombies might be a reference to Demoni.
- And on the video game side, the ultra-strong zombie at the end is similar to the Tank from Left 4 Dead.
- The zombie chick who almost bites the main character before Rigby bumps into the projector might be a nod to the "horror hags" from the original Evil Dead.
