Poppy Playtime Chapter 4 delivers answers, but also throws up a whole new batch of questions. Need help deciphering the convoluted ending, full of grudges and grand ambitions? Let's break it down.
What Does the Poppy Playtime Chapter 4 Ending Mean?

Poppy Playtime Chapter 4 is a rollercoaster. While Safe Haven initially offers a sense of security, that feeling is short-lived. Despite defeating Barnaby and the Doctor, things take a dark turn. The Prototype, aware of Poppy's explosive plan, moves the explosives to destroy Safe Haven. This act shatters Doey, turning him aggressive. After defeating him, we find Poppy and Kissy Missy in hiding.
Here's the major twist: Ollie, our supposed ally, is revealed to be The Prototype. This creepy villain can change his voice, expertly mimicking others. He uses this ability to deceive Poppy, making her believe he's Ollie.
While Poppy always portrays The Prototype as pure evil, their history is more complex. A VHS tape found during the Doey chase scene shows Poppy crying after a moment of joy. The Prototype convinced her they could escape the factory, a promise he broke.
The Prototype argues escape is impossible; they're monsters, unacceptable to humans. Despite her hatred of the factory, Poppy understands and agrees to his logic, leading to her decision to destroy the factory to prevent more victims.
However, The Prototype anticipates Poppy's plan. Using his guise as Ollie, he thwarts her efforts, threatening to imprison her again. His motives for keeping Poppy captive remain unclear, but the threat forces her to flee.

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

With Poppy gone, The Prototype sets his sights on destroying the player's hiding place. Kissy Missy's injured arm snaps as she attacks, but we survive, only to find ourselves in a lab. This lab contains a poppy garden, the source of the factory's experiments.
This area is likely the final setting in the Poppy Playtime series. Poppy previously stated this is where The Prototype hides and keeps orphaned children. We'll probably need to defeat the final boss, rescue the children, and destroy the factory. The journey won't be easy; navigating the lab's security will be a challenge.
We'll also face Huggy Wuggy, seemingly intent on devouring us. His wounds suggest he's the Huggy Wuggy from Poppy Playtime Chapter 1, even sporting bandages. These injuries won't deter his attempts to tear us apart.
That's the Poppy Playtime Chapter 4 ending explained. We're nearing the climax, a final confrontation with the boss before escaping this nightmarish factory.
