All Momento Dino Bedroom Puzzle Solutions (Xylophone, Crayons, Dolls)

The complete solution for the Dino Bedroom puzzle in Momento requires you to first solve three sub-puzzles—the xylophone, the crayons, and the dollhouse—to collect three of the four colored dinosaur figures. The final figure is hidden in the room. Once all four are collected, you must place them on a diorama in the correct order, which activates a star projector revealing the final code to unlock the door key from a toy safe.

This guide breaks down every single step, ensuring you can bypass any frustrating blockades and appreciate the room's clever design.

01

The Core Objective: Finding All Four Dinosaur Figurestag

Your primary goal in the Dino Bedroom isn't to escape directly, but to find four specific toys: a Red T-Rex, a Green Stegosaurus, a Blue Triceratops, and a Yellow Pterodactyl. These four figures are the keys to the final puzzle. They must be placed on a large dinosaur diorama in the center of the room, which has four pressure-sensitive pedestals. Each puzzle you solve will reward you with one of the figures, with the last one rewarding simple, thorough exploration.

Here's the breakdown of which puzzle yields which dinosaur:

• Xylophone & Music Box Puzzle: Rewards the Green Stegosaurus.
• Crayon Color-Block Puzzle: Rewards the Blue Triceratops.
• Dollhouse Arrangement Puzzle: Rewards the Red T-Rex.
• Simple Search: Rewards the Yellow Pterodactyl.

How to Solve the Xylophone and Music Box Puzzletag

This multi-part puzzle links a piece of sheet music to a toy xylophone, which in turn unlocks a nearby music box. It's a classic escape room sequence of observation and execution.

Step 1: Find the Sheet Musictag

The clue is hidden in plain sight. On the bookshelf against the far wall, there is a collection of children's books. Inspect the one titled Dinosaur Dreams. Tucked inside its pages is a torn piece of sheet music. The notes themselves aren't important if you can't read music; the key is that each note head is colored in with crayon.

Step 2: Interpret the Color Sequencetag

Lay the sheet music out and look at the toy xylophone on the floor. You'll see each metal bar is painted a different color. The sequence of colored notes on the page is your melody. The correct order to play is:

1. Red
2. Yellow
3. Blue
4. Green
5. Red
6. Orange

Step 3: Play the Melody and Claim the Green Stegosaurustag

Use the small mallet next to the xylophone to strike the colored bars in the exact sequence from the sheet music. If you play it correctly, you'll hear a small click sound from the ballerina music box on the dresser. The drawer at its base will pop open. Inside, you'll find the Green Stegosaurus figure. Take it.

Cracking the Crayon Color-Block Codetag

This puzzle is a pure logic and observation challenge centered on a locked crayon box sitting on an art easel. The solution is found in a child's drawing pinned to a corkboard on the wall.

Step 1: Locate the Drawing and the Locked Boxtag

First, examine the drawing on the corkboard. It depicts four simple, bold shapes, each colored in with a specific crayon: a bright red square, a deep blue circle, a sunny yellow triangle, and a forest green star. Next, turn your attention to the large wooden crayon box on the easel. It's locked with four rotating dials, each featuring the same four shapes.

Step 2: Match the Shapes to the Colorstag

The puzzle's logic is to set each dial on the box to match the color-shape combination from the drawing. The box doesn't care about the order of the dials, only that each shape is correctly assigned its color from the artwork. This is a common point of confusion; players often try to find a sequence, but it's a matching task.

Step 3: Set the Dials and Find the Blue Triceratopstag

Rotate the dials on the crayon box until they show the following combination:

• The Square dial is pointing to the Red color swatch.
• The Circle dial is pointing to the Blue color swatch.
• The Triangle dial is pointing to the Yellow color swatch.
• The Star dial is pointing to the Green color swatch.

Once all four are correctly set, the lid of the crayon box will unlock. Lift it to find a pile of crayons and, nestled among them, the Blue Triceratops figure.

04

Arranging the Dolls in the Dollhousetag

This puzzle requires you to interpret a narrative clue from a diary to correctly stage a scene in the large dollhouse sitting in the corner of the room.

Step 1: Find the Clue in the Diarytag

On the nightstand next to the bed is a child's diary, left open to a specific page. The entry describes an imaginary tea party: "Mom got me a new Astronaut doll! I had a tea party for him. The Astronaut sat across from the Cowboy, and the Doctor sat next to the window to look at the garden. The Firefighter was busy." This text is your complete set of instructions.

Step 2: Place the Three Dolls Correctlytag

Gather the three dolls mentioned—the Astronaut, the Cowboy, and the Doctor—which are found scattered around the room. Now, look inside the dollhouse. You'll see a small dining room with a table and four chairs. Two of the chairs are positioned next to a tiny window.

Following the diary's instructions:

1. Place the Doctor doll in one of the two chairs next to the window.
2. Place the Astronaut and Cowboy dolls in the two chairs that are directly across from each other.
3. The fourth chair remains empty, as the Firefighter was "busy."

Step 3: Retrieve the Red T-Rextag

As soon as the three dolls are in their correct positions, you'll hear a mechanical whirring sound. The oversized brick chimney on the roof of the dollhouse will slide open, revealing a hidden compartment. Inside is the Red T-Rex figure. This is the third of the four dinosaurs you need.

The Final Diorama and Star Projector Puzzletag

With three dinosaurs in hand, you're ready for the final sequence. This involves finding the last figure, placing all four correctly on the diorama, and using the resulting clue to open the toy safe.

Step 1: Find the Yellow Pterodactyltag

This is the simplest but most frequently missed step. The final dinosaur isn't locked behind a complex puzzle. The Yellow Pterodactyl is hidden under the pillow on the bed. Lift the pillow to find it. This design choice rewards players for thoroughly searching their environment.

Step 2: Place the Dinosaurs on the Dioramatag

Now, approach the large dinosaur diorama on the floor. It has four empty pedestals, each set against a different backdrop: a volcano, a dense forest, a small lake, and a rocky cliff. The clue for the correct placement is on the wallpaper border running along the top of the room's walls. The repeating pattern shows each of the four dinosaurs in its natural habitat.

• The T-Rex is shown roaring in front of a volcano.
• The Stegosaurus is shown eating leaves in a forest.
• The Triceratops is shown drinking from a lake.
• The Pterodactyl is shown perched on a cliff.

Place each figure on its corresponding pedestal:

• Red T-Rex on the Volcano pedestal.
• Green Stegosaurus on the Forest pedestal.
• Blue Triceratops on the Lake pedestal.
• Yellow Pterodactyl on the Cliff pedestal.

Step 3: Use the Star Projector to Unlock the Safetag

Placing the last dinosaur correctly completes a circuit, and the star projector lamp on the nightstand will turn on, casting a starfield onto the ceiling. Look up. Among the dozens of stars, four will shine significantly brighter than the rest. They form a distinct pattern that resembles the Big Dipper.

Now, look at the toy safe near the door. It has a 4x4 grid of unlabeled buttons. Your task is to press the four buttons that match the positions of the four bright stars in the constellation. Once you press the correct four buttons, the safe will click open. Inside is the shiny brass key to the bedroom door. Use it to escape.

Frequently Asked Questionstag

Where is the last dinosaur figure in the Dino Bedroom? The last dinosaur, the Yellow Pterodactyl, is the one most players miss. It is not locked behind a multi-step puzzle. You can find it by simply lifting the pillow on the bed.

What is the xylophone code in Momento? The sequence is not based on musical notes but on the colors shown in the sheet music found in the Dinosaur Dreams book. The correct order to strike the keys is: Red, Yellow, Blue, Green, Red, Orange.

I placed the dolls in the dollhouse but nothing happened. What am I doing wrong? Check your placement against the diary entry precisely. The Doctor must be in a chair next to the window, and the Astronaut and Cowboy must be directly opposite one another. If they are sitting next to each other, or if the Doctor is not by the window, the puzzle will not trigger.

Is there a time limit in the Dino Bedroom? No, there is no time limit for this room in Momento. You can take as much time as you need to explore and solve the puzzles without any pressure.

Final Thoughtstag

The Dino Bedroom is a masterclass in puzzle design, forcing the player to link observation, logic, and environmental storytelling. Every clue is present in the room, but success hinges on your ability to see the connections between a child's drawing, a diary entry, and the toys left scattered about. It’s less about brute force and more about stepping into the mindset of the room's former occupant.
