Poppy Playtime Chapter 4 provided answers, but also ignited a fresh wave of questions. Let's unravel the tangled web of grudges and ambitions that concluded this chapter.
What Does the Poppy Playtime Chapter 4 Ending Mean?

Poppy Playtime Chapter 4 is a rollercoaster of twists and turns. While Safe Haven initially offered a sense of security, that illusion quickly shatters. Despite defeating Yarnaby and the Doctor, our heroes face new threats.
The Prototype learns of Poppy's explosive plan and acts swiftly to redirect them, triggering a devastating attack on Safe Haven. This event deeply affects Doey, turning him aggressive. After overcoming Doey, we encounter the hiding Poppy and Kissy Missy.
Here's the major revelation: Ollie, our seemingly trusted ally, is revealed to be The Prototype. This cunning villain possesses the ability to alter his voice and impersonate others, expertly deceiving Poppy into believing he's Ollie.
While Poppy consistently portrays The Prototype as the antagonist, their history runs deeper. A VHS tape discovered during the chase with Doey reveals Poppy's heartbreak after a period of supposed happiness. The Prototype convinced her they could escape the factory, a promise he never intended to keep.
The Prototype claims escape is impossible; they've been transformed into monsters, unacceptable to the outside world. Despite her hatred for the factory, Poppy understands and agrees with The Prototype's assessment. This understanding, however, leads her to plan the factory's destruction to prevent further transformations.
The Prototype, ever vigilant, anticipates Poppy's plan. Using his guise as Ollie, he thwarts her efforts and threatens to imprison her again. The reason for this hostage situation remains unclear, but the threat forces Poppy's panicked escape.

What's the Deal With the Laboratory in Poppy Playtime: Chapter 4?

Following Poppy's departure, The Prototype initiates the destruction of the player's hideout. Despite Kissy Missy's attempt to capture us, her injured arm fails, leaving us vulnerable but alive. We find ourselves inside the laboratory, a garden of poppies used in the factory's experiments.
This area is likely the final setting in the Poppy Playtime series. Poppy previously revealed this location as The Prototype's hideout, where he keeps orphaned children. The final confrontation likely involves saving these children before destroying the factory. This won't be easy, as navigating the lab's security is crucial.
The player will also face Huggy Wuggy, seemingly intent on devouring us. His injuries suggest he's the Huggy Wuggy from Poppy Playtime Chapter 1, possibly even bandaged by someone. These injuries, however, won't deter his attack.
This summarizes the ending of Poppy Playtime Chapter 4. We're nearing the climax, facing the final boss before escaping this nightmarish factory.
