Detective Duck The Museum Walkthrough (Clue, Codes)

The Museum is one of those maps where everything feels straightforward at first—until you realize the game expects you to actually pay attention to small environmental clues. From hidden keys to timeline evidence, this case is more about observation than difficulty.

Here’s the full walkthrough with every step, code, and clue explained clearly.

First Clue – “Fragile” Hint

At the start, use your magnifying glass on the boarded section, because it reveals the hint:

“Fragile – use crowbar”

This tells you exactly what tool you need next.

Finding the Crowbar

Head to the end of the hallway, where you’ll find the Crowbar, which is required to break open the wooden boards.

Hidden Key Behind the Boards

Use the crowbar on the wooden planks, since breaking them reveals a key, which is used to unlock the next room.

Antique Room → Artwork Key

Use the key to enter the Antique Room, then inspect the plant, because searching it gives you the Artwork Room Key.

Artwork Room Puzzle (1550 Code)

Inside the artwork room, focus on the painting labeled:

Brunell Mural – Year: 1550

Now move to the locked door nearby and use your magnifying glass, which confirms:

“It’s the year of the mural”

So enter:

Code: 1550

Construction Room Key

After unlocking the door, check the stack of papers, because the last page gives you the Construction Room Key.

Construction Room → USB

Go to the construction room and open it using the key, then pick up the USB device, which is needed for the security system.

Security Room – USB Authentication

Return to the security room, press the red button to activate the system, and insert the USB, which begins loading the data.

Lockpick Tool + Janitor Room

While the system is loading, grab the lockpick tool, then head to the janitor room and use the lockpick correctly three times to unlock it.

Evidence Gathering – Key Clues

Now comes the important part—figuring out the suspect using evidence.

1. Muddy Boots (Construction Room)

In the construction room, you’ll notice muddy footprints, which indicates someone working there moved into other areas.

2. Footprints Near the Crown

In the artwork room, use your magnifying glass to spot footprints leading to the crown, showing exactly where the thief went.

3. Suspicious Worker Behavior

Notes mention that a worker kept asking about construction room keys, which already sounds suspicious.

4. Timeline Evidence (Security Footage)

From the system logs:

• 2:00 PM → Elias (worker) arrives
• 2:50 PM → Construction room active
• 3:39 PM → Elias seen near the receptionist (hands raised)
• 5:00 PM → Crown is missing

This timeline clearly places him at every key moment.

Connecting the Clues

When you put everything together:

• Muddy boots match construction worker
• Footprints lead directly to the crown
• Suspicious behavior with keys
• Timeline confirms presence during the theft

There’s only one person who fits all of this.

Correct Suspect

Elias (The Worker / “Glacier”)

Ending the Investigation

Select Elias as the suspect and confirm your choice to successfully solve the museum case.

Quick Recap

• Crowbar → Break Boards
• Antique Room Key → From Boards
• Artwork Code → 1550
• Construction Key → Papers
• USB → Construction Room
• Lockpick → Janitor Room
• Evidence → Footprints + Mud + Timeline
• Suspect → Elias

This case is less about puzzles and more about connecting evidence logically. Once you start paying attention to details like footprints and timelines, the answer becomes obvious without any guesswork.
