The latest Animal Hospital update introduces much more than a simple content patch. Along with several brand-new class skins, players can now encounter a mysterious Ghost Anomaly that behaves differently from previous events. On top of that, the update expands the game’s hidden story by revealing more about Ratthew and his missing sister through a secret questline. If you want to see everything added in the Anomaly Update, here’s a complete breakdown of the new features and hidden secrets.

New Class Skins

One of the biggest additions is the new skin system. You can access it by opening the Classes menu and selecting the Skins tab at the top of the screen. Several classes have received new cosmetic appearances. The newly added skins include:

  • Intern – Rascal
  • Nurse – Assistant Nurse
  • Psychologist – Psycho
  • Security – Hospital Cop
  • Head Nurse – Supervisor
  • Secret Agent – Agent Ratthew

At the moment, the Secretary, Doctor, Surgeon, and Paramedic classes have not received any new skins in this update.

Meet the New Ghost Anomaly

The highlight of the update is the mysterious Ghost Anomaly, which can randomly appear throughout the hospital. Unlike other hazards, the ghost interacts with the environment in unusual ways. During gameplay, it has been seen opening and closing doors and interacting with nearby objects, making it feel more like a living entity than a standard event. If the ghost comes into contact with your character, you’ll lose 2 Sanity due to its ghostly presence.

Can You Defeat the Ghost?

Many players have experimented with different tools to stop the Ghost Anomaly. Current observations suggest:

  • Fire extinguishers do not affect it.
  • Using a Taser causes the ghost to disappear.
  • The Taser doesn’t appear to lose its charge after being used on the ghost.

The full behavior of the anomaly is still unclear, so players are continuing to test different interactions to discover its hidden mechanics.

Ratthew’s Hidden Story

Animal Hospital Anomaly Update Guide – New Skins, Ghost Anomaly, Hidden Lore, and Secrets

The update also expands the game’s lore through conversations with Ratthew. If you continue speaking with him over multiple interactions, he’ll eventually begin sharing a personal story. Ratthew explains that he once had a sister named Rattina, who previously worked at the Animal Hospital corporation.

According to Ratthew, she suddenly disappeared without leaving behind any explanation or goodbye. As the conversation progresses, Ratthew eventually leaves you with a mysterious key along with a note claiming he took it from the doctor.

How to Unlock the Secret Room

After receiving the key from Ratthew, you can uncover another hidden secret inside the hospital. Follow these steps:

  1. Take the key given by Ratthew.
  2. Visit Room Number 5.
  3. Remove the cat poster hanging on the wall.
  4. Reveal the hidden lock behind the poster.
  5. Use the key to open the secret compartment.

Inside, you’ll discover a photograph of Rattina along with another important clue connected to the hospital’s experiments.

The Hidden Experiment Note

The secret room also contains a note that reads: “The experiment was a success. The shadow now sees everything.”

This message appears to confirm that Rattina’s disappearance is connected to the mysterious experiments taking place inside the hospital. Earlier pieces of lore hinted that unusual testing was happening behind the scenes, and this latest discovery strengthens that theory. While many questions remain unanswered, the update clearly pushes the game’s story in a darker direction.

Other Changes in the Update

Besides the new skins and lore additions, the update also includes a small gameplay fix. The previously known Infinite Charge bug has been patched, preventing players from exploiting unlimited charges during gameplay. Although it’s a minor change compared to the new content, it improves the overall game balance.

What We Still Don’t Know

Even after exploring the update, several mysteries remain unsolved. Players are still trying to learn:

  • Why the Ghost Anomaly appears.
  • Whether it has additional interactions.
  • If more hidden lore can be unlocked.
  • Whether Rattina is still alive.
  • What the “Shadow” mentioned in the note actually is.

Future updates may reveal more answers as the storyline continues. The Anomaly Update adds far more than new cosmetics. Between the Ghost Anomaly, the hidden story involving Ratthew and Rattina, secret room discoveries, and the expanded lore surrounding the hospital’s experiments, this update gives players plenty of reasons to keep exploring.

If you’re interested in uncovering every mystery, make sure to talk to Ratthew multiple times, collect the hidden key, and investigate Room Number 5. While the Ghost Anomaly remains largely unexplained, it’s clear that this update is laying the foundation for a much larger story in future Animal Hospital updates.
