Despite the Happy Tree Pizzeria being shut down for good, Flippy and Petunia turn their careers as security guards to another company known as Happy Tree Weapons and Tactical Arms
They thought that they only needed to look after the warehouse at night together. But what they didn't know was that part of the spirits of the four children possesses the animatronics that are prototypes for weapons to fight wars across the world.
