Hidden Rooms in Chapter 3 APK Version – Locations Only Mod Players Can Access
One of the main reasons the Poppy Playtime Chapter 3 APK MOD is still popular in 2025 is its exclusive access to hidden rooms and secret areas. These are not available in the official version of the game. If you want to enjoy this, you need an APK mod version to unlock. If you’re a mobile player and using the Apk version of Chapter 3, you are experiencing some deep lore, creepy details, and content most players never see.
In this article, I will show you 2,3 hidden rooms you can only access using the APK MOD menu, also give you guys guide on how to reach these secret rooms, and what you will find inside these secret rooms, including some lore Easter eggs that you don’t want to miss.
💡 I tested these rooms using a modded APK on Android 13, and there were no crashes, and the secret rooms are legitimate.
What You Need to Unlock Hidden Rooms
To access these secret locations, make sure you have:
- ✅ APK version Of poppy playtime 3
- ✅ Mod menu installed (look for features like “fly,” “wall hack,” or “unlock all doors”)
- ✅ Android 6.0 or higher
- ✅ Latest version of Chapter 3 (v1.0.7 or above)
Hidden Room 1: Prototype Observation Chamber
This room hints at where the prototype was tested or kept. In the original game version, this room is locked, but if you are using the APK modded version, you can go inside and enjoy everything.
✅ Where you can Find it? You will find this room behind the locked red door near the Playcare Security.
✅How to Access: Use “noclip” from the mod menu or unlock all doors from the debug options
🧩What’s Inside This Room?
- Many destroyed monitors and tables with red stains
- Audio logs (untranslated, possibly future update placeholders)
- A sealed glass chamber labeled “Prototype”
- A flickering screen that flashes and shows static messages
Hidden Room 2: Playcare Storage Level B
This room is normally unreachable during the original version or PC gameplay. The notes taped on the walls mention failed bonding between “gas-induced subjects” and “sentient playtime models.” That could connect to CatNap’s role in Chapter 4.
✅ Where you can Find it? You can access this location at Lower level of Play care.
✅How to Access:Use a free camera or fly mod, teleport to coordinate B2-Ax133.
🧩What’s Inside This Room?
- You can find a stack of dolls and their parts labeled “Retired.”
- An early sketch of Huggy Wuggy and CatNap
- Handwritten notes taped to the walls (partially readable)
“This was the creepiest room for me. It was totally hidden unless you fly, and the audio changes too, which gave me goosebumps.”
Hidden Room 3: Train Maintenance Tunnel
This tunnel might be used for a secret ending or a hidden death route. The mod version gives you access to walk right through the final door that, in the normal version, ends the chapter.
✅ Where you can Find it? You can find this below the train escape sequence.
✅How to Access: Use teleport or noclip during the escape scene.
🧩What’s Inside This Room?
- A paused CatNap clone model in a pause pose
- Unused steam/fog effects
- Door labeled “Do Not Power – Last Exit”
Why PC Players Can’t See These Rooms?
Players that play the original version can’t access these rooms because the game blocks them with walls or locked doors. But in the apk mod version you have some special tools which helps players to reach these hidden rooms and secret areas that are normally hidden in the original normal version of the game.
Special tools in APK MOD MENU
- Wall hacks / noclip
- Camera freedom
- Developer/debug style access
- Exploration of unlinked or cut scenes
Final Thoughts
First time when I played the modded APK version of Poppy Playtime Chapter 3, I was honestly shocked by what I am experiencing because I have found out these hidden rooms that were not just some empty areas but actual unfinished part of the game.
Using the mod menu, I was able to fly through the locked doors, and explore rooms that are not even mentioned in the official version. It felt like digging through a creepy part of the game that was meant to stay secret.
If you’re a true fan of this game and love uncovering hidden lore and details, I really recommend checking out the mod version. You’ll see parts of the story and environment that completely change how you look at Chapter 3.
