Poppy Playtime Chapter 4 Hangman Puzzle Code and Solution

The first coded puzzle is located in the cell block area. Ascend the stairs to the top floor and enter the observation area. Inside, you'll find a code terminal, a red button, and a whiteboard. A second red button near a large animal cutout is purely decorative.
The code is the numerical equivalent of the letters in the Hangman game's winning word: CELL.
The code is: 3255. Press the red button after entering the code to unlock the door at the far end of the cell block.
Poppy Playtime Chapter 4 Cage Calendar Puzzle Code and Solution

Solving this puzzle clears the red smoke from the prison block. Quickly navigate to the upstairs control room. Near the front window is a code panel; a whiteboard to its right has a sticky note instructing you to "check the CAGE." The top calendar row displays four scrambled letters. The code consists of the numerical values corresponding to the letters in "CAGE." (C=3, A=6, etc.)
The complete code is: 3642. The smoke will dissipate, allowing you to exit through the newly broken window to your left. While you can return downstairs, there are no further discoveries there.
Poppy Playtime Chapter 4 Prison Tower Puzzle Code and Solution

Following the encounter with Doey, you'll find yourself trapped in the prison's recreation yard. Climb the stairs and enter the office atop the blue tower to find a code terminal and a whiteboard listing colors. This list, along with the numbers on each tower (specifically, the second number on each), provides the solution.
The correct sequence is the second number on each tower, ordered according to the listed colors (blue, green, yellow, red). The blue tower's second number is missing; however, the sequence on the other towers dictates it must be 33.
Therefore, the final code is: 3021. Retrieve the lever from the locker, insert it into the blue panel in the prison yard, attach chains from each tower to the door, and pull the levers to open it.
Poppy Playtime Chapter 4 Secondary Labs Puzzle Code and Solution

The Secondary Labs puzzle requires matching numbers to stuffed animal anatomy images. Determining the correct number order is more complex than the other puzzles in this chapter. First, locate the remains of each experiment and interact with it to add its number to the database. Many rooms in the Doctor's Domain are filled with red smoke.
While you now possess a gas mask, its protection is limited. The most efficient approach involves exploring the gas-filled maze in short bursts, returning to the operating room to refill your oxygen tank using the dispenser.

However, there's a caveat. The experiments are hidden within a maze filled with red gas. Poppy Playtime relies on sound and dialogue cues to guide you to each experiment. These sounds intensify as you approach; however, if you have hearing difficulties or are in a noisy environment, you'll need to explore the maze thoroughly.
Returning to the operating room reveals each experiment on a monitor with a number sequence. The last number in each sequence is the code number; the anatomy chart next to the dispenser indicates the correct order: head, right arm, left hand, right leg, left foot.
Alternatively, you can bypass this and enter the code directly: 35198.
With these puzzle codes, you're well-equipped to navigate towards the unsettling conclusion of Poppy Playtime Chapter 4.
