The latest Animal Hospital update introduces a hidden secret that expands the game’s storyline. Players can discover a locked compartment hidden behind a poster, but opening it requires a special key that isn’t immediately available. If you’re wondering how to unlock the secret door and reveal what’s hidden inside, this guide walks you through every step.
Talk to Ratthew Multiple Times
The first thing you need to do is find Ratthew, one of the friendly rat patients in the hospital.
Simply speaking with him once isn’t enough. You’ll need to continue interacting with him over multiple conversations until he starts sharing more of his personal story.
Eventually, Ratthew explains that he had a sister named Rattina, who worked at the Animal Hospital corporation before mysteriously disappearing. As the dialogue continues, he’ll eventually trust you enough to hand over an important item.
Obtain the Secret Key
After progressing through all of Ratthew’s conversations, he’ll leave you with a key and a short note. According to the note, the key originally belonged to the hospital’s doctor, making it an important clue connected to the hidden mystery surrounding the hospital. Without this key, you won’t be able to access the secret room.
Go to Room Number 5
Once you have the key, make your way to Room Number 5 inside the hospital. Carefully inspect the room until you find a cat poster hanging on the wall. At first glance, it looks like ordinary decoration, but it’s actually hiding something important. Interact with the poster to remove it.
Open the Secret Door
After removing the poster, you’ll discover a hidden lock behind it. Use the key that Ratthew gave you to unlock the hidden compartment. Once opened, you’ll reveal one of the game’s biggest lore secrets introduced in the latest update.
What’s Inside the Secret Room?
Opening the hidden compartment rewards you with several important story clues. Inside, you’ll find:
- A photograph of Rattina, Ratthew’s missing sister.
- A mysterious document.
- A note mentioning a successful experiment.
The note states:
“The experiment was a success. The Shadow now sees everything.”
This message strongly suggests that Rattina’s disappearance is connected to the strange experiments taking place inside the Animal Hospital.
Why Is This Secret Important?
The hidden room provides one of the clearest pieces of lore currently available in the game. Previous dialogue hinted that mysterious experiments were being conducted within the hospital, but the hidden note confirms that something much larger is happening behind the scenes. It also explains why Ratthew has been searching for his missing sister and adds more depth to one of the game’s most emotional storylines.
Unlocking the secret door in Animal Hospital doesn’t reward you with powerful equipment or gameplay bonuses, but it does reveal one of the most interesting pieces of hidden lore in the game. The discovery connects Ratthew, his missing sister Rattina, and the mysterious experiments taking place throughout the hospital.
If you enjoy uncovering hidden secrets and following the game’s story, this is one mystery you won’t want to miss. Keep an eye out for future updates, as it’s likely this storyline will continue to expand with even more secrets waiting to be discovered.
