General Survival Strategies

Watch Your Stamina: Sprinting produces heavy footstep noise that attracts nearby monsters. Reserve your sprint meter for platforming jumps and scripted chases.
Inspect Every Fossil: Many interactive ledges blend directly into dinosaur skeletons and decorative museum rockwork. Look for subtle ledges and climbable yellow pipes.
Keep Your Flashlight Charged: Dark zones—especially the basement—hide critical interaction points like fuses and junction boxes in pitch-black corners.
Listen for Audio Cues: Mascot animatronics emit mechanical groans and heavy thuds before entering a room. Use your surroundings to break line of sight.

Item / Mechanic	Primary Function	Found In
Tokens	Unlocks gates and dispenses vital gear like the Flashlight	Reception & Exhibits
Flashlight	Illuminates pitch-black areas like the basement	Exhibit Vending Machine
Headphones & Radio	Lore items / Narrative progression triggers	Security Control Room
Yellow Pipes	Stable climbing and traversal bars	Backstage & Hallways
Fuses (x3)	Restores commercial power to display pillars	Flooded Basement

Arrival and Reception: Cracking the First Keypad Puzzle

Your nightmare begins outside Dalton's Dinos after stepping out of your disabled car. Approach the illuminated payphone near the main front doors to attempt an emergency call. With the lines dead, push open the heavy double doors to enter the reception atrium.

The main hall features towering skeletons of ancient apex predators. The doorway to the employee-only sector is sealed shut with an electronic security keypad. To unlock it, you must locate two torn halves of an access memo scattered across the room.

First Note Half: Head to the left side of the atrium where the large Allosaurus fossil stands. Climb onto the nearby artificial rock outcropping to reach the skeleton's right hand. Snatch the scrap of paper tucked between its fossilized claws.
Second Note Half: Walk across the atrium floor toward the giant Brontosaurus skeleton on the right. Search around the base of its pedestal to discover the matching piece.

Combining both pieces reveals the four-digit master code: 9216.

Enter 9216 into the employee door keypad. Inside the office, pick up the brass amusement token sitting on the front desk. Insert this token into the turnstile slot beside the theater doors to open the pathway forward.

Keypad Location	Solution Code	Clue Location
Reception Employee Door	`9216`	Torn memo split between Allosaurus and Brontosaurus
Gift Shop Basement Access	`1903`	Discovered via Office VHS tape memo & documentation

The Theater and Security Terminal: Restoring Exhibit Power

Proceed inside the theater auditorium and take a seat to trigger the automated preshow. After a short cinematic presentation, the power malfunctions, plunging the auditorium into red emergency lighting. A service door labeled No Entry will click open along the perimeter wall.

Head through the door into the backstage staging wing. Here, your parkour skills are tested for the first time in this Terrible Lizards walkthrough.

Stack your footing atop the wooden shipping crates on the left to gain height.
Sprint and leap toward the top edge of the wire storage cage, pulling yourself over.
Drop onto the back of the animatronic dinosaur display on your right.
Jump across the spine of the model, leap onto the catwalk overhead, and duck beneath the steam pipes.

Follow the linear maintenance corridor until you reach the central security control room. Interact with the computer console on the desk. The system reports that main gate power is offline, requiring you to manually trigger three breaker switches placed throughout the exhibit hall.

Breaker Switch	Location Description	Traversal Required
Switch 1	Atop the right exhibit dinosaur	Climb body contours; descend back via ladder
Switch 2	Upper balcony overlooking main stage	Scale stage rigging; leap across artificial branches
Switch 3	High platform right of security room	Hop stacked crates to reach upper service rail

After activating all three switches, return to the security room and pull the large master breaker lever. Before walking through the newly unlocked exit gate, make sure to collect the telephone and headphones resting on the counter beside the dispatch radio.

Dilo Dash to Backstage: Flashlight and Mascot Traversal

Stepping beyond the security gate leads you straight into the park's Dilo Dash attraction. The floor in this area is covered in live, exposed electrical cables. Touching the floor results in immediate death, so you must carefully leap from platform to platform.

Make your way toward the back service alley. Look up to spot horizontal yellow pipes running between the brick walls. Shimmy across these pipes, drop safely onto the opposite platform, and enter the adjacent attraction hall.

Climb the decorative stone pillars flanking the entrance. At the highest point of the pillar sequence, turn right to spot an isolated ledge holding a shiny amusement token. Grab it, descend to the floor level, and insert the token into the prize dispenser on the right side of the hall to obtain your Flashlight.

With illumination secured, follow this section of our Terrible Lizards walkthrough to navigate the blocked exit:

Jump onto the glass display case to reach the overhead rafters.
Look for the overhead track carrying moving dinosaur dummies.
Time your jump to grab onto a passing dummy. Let it carry you across the chasm, then drop onto the supply crates on the far side.
Pick up the mechanical Push Button resting on the crates.
Slide under the tail of the stationary dinosaur to your left, scale the right-hand pillars, and squeeze through the ceiling duct.

The Gift Shop and Basement: Fuse Boxes and Mascot Evasion

Climb down the maintenance ladder at the end of the duct and hop across the yellow pipe barrier. Crawl through the low vent on your left to drop directly inside the Dalton's Dinos Gift Shop.

Cross the retail floor and unlock the back manager's office. Play the VHS tape inside the VCR and listen to the audio logs from Stella. Once the conversation concludes, exit into the hallway, turn right, and follow the corridor left toward the basement stairwell.

Punch code 1903 into the heavy security keypad to unseal the basement door. Switch on your flashlight and head down into the dark storage vault to collect three industrial fuses.

Fuse Location	Detailed Position	Threat Level
Fuse #1	Straight ahead from the basement stair entrance	Low (Safe zone)
Fuse #2	Rear corner of the basement, slightly to the left	Moderate (Zero visibility)
Fuse #3	Far left storage alcove behind shelving	High (Tight corners)

Once you gather all three fuses, return to the gift shop level. As soon as you emerge, the park's predatory dinosaur mascot begins actively hunting you. Community reports show that attempting to outrun the mascot in straight lines often drains your stamina too early; instead, use merchandise displays to loop the creature and break line of sight.

Run to the three support pillars located across the facility to install the fuses:

Office Pillar: Near the manager's office door. Place the first fuse when the mascot is trailing far behind.
Toy Section Pillar: Located amid the plushie racks. Loop around the display cases before inserting the second fuse.
Arcade Pillar: Standing just outside the arcade entrance. Insert the final fuse, then sprint into the arcade itself.

Inside the arcade, take an immediate left to locate an open wall vent. Crawl through to escape the mascot's grasp and access the upper rafters.

The Bronto Chase: Floodlight Activation and Cavern Escape

From the rafter walkways, you must pull three overhead breaker levers positioned directly above the three fuse pillars you just powered. Carefully hop across the hanging beams to engage each lever. After the third lever is pulled, crawl through the ceiling duct to drop back inside the manager's office.

Now comes the most intense survival sequence highlighted in this Terrible Lizards walkthrough. A colossal, mutated Brontosaurus has broken through the central floor, patrolling the lower levels while you scramble to illuminate the room.

To permanently drive the beast away, you must revisit the three ground-level fuse boxes and manually switch on the industrial floodlights.

Stealth Over Speed: Avoid sprinting unless the monster actively targets you. Walking keeps your footstep volume low, allowing you to slip past its massive legs.
Light Activation: Interact with each fuse box to flood the hall with blinding halogen light.
The Exit Trap: Once all three floodlights ignite, sprint toward the primary exit doors located to the right of the manager's office.

Just as freedom seems within reach, the Brontosaurus smashes through the ceiling, obliterating your exit door in a flurry of debris. Immediately spin 180 degrees and sprint down the newly collapsed hallway straight ahead. Leap over broken concrete slabs and pipe gaps, following the descending tunnel down into the ancient subterranean caverns. Reaching this underground sanctum triggers the final cutscene, bringing Chapter One to a close.

Frequently Asked Questions

What are the keypad codes for Chapter One?

There are two essential keypad codes featured in this Terrible Lizards walkthrough. The reception employee door code is 9216 (found by piecing together two torn notes from the Allosaurus and Brontosaurus skeletons). The gift shop basement access door code is 1903.

How do you avoid the mascot in the gift shop?

The mascot relies heavily on direct line of sight and sound. When placing fuses into the three pillars, never run directly between them in a straight line. Use the tall toy shelving, retail display counters, and arcade partitions to loop the creature. Only interact with a fuse box once you have created at least five to ten paces of separation.

What should you do if you touch the floor in Dilo Dash?

The floor in the Dilo Dash section is completely electrified and causes instant death upon contact. If you slip off the display pedestals or yellow pipes, you will immediately reload at the previous checkpoint. Take your time timing your jumps across the moving platforms and animatronics rather than rushing through the attraction.
