Terrible Lizards Achievement & Collectibles Guide: All 15 Achievements, 24 Chapter 2 Notes & DBD Codes
Direct Answer: Terrible Lizards (`App ID 2920220`) features 15 Steam achievements: 1 museum entry milestone (`97.7%`), 4 level completions (`76.5%` down to `21.8%`), 5 rare collectible challenges (`0.1%` to `0.3%`), and 5 environmental interactions or deaths. Below is the complete decoded schema, the Dead by Daylight redemption workflow, and an interactive audit of all 24 Chapter 2 notes so you never get stuck at `23/24`.
Completionist Angle: While Steam hides 14 of 15 achievement descriptions and players often assume Chapter 2's `23/24` note counter is broken, every `0.1%` collectible achievement is obtainable in Patch v1.0.9 once you climb into the hidden upper opening right above the post-balance-beam tunnel exit for the missing Adrenaline Junkie note.
1. Complete 15-Achievement Decoded Schema & Global Rarity (`2026-11-01`)
Only Welcome to Dalton's Dinos displays its description publicly on the Steam store page; the remaining 14 are masked as hidden achievements. We extracted the underlying schema (`queryKey: ["achievements", 2920220, "schema_v2"]`) and global unlock percentages (`ach_pct.json`) directly from Steam Community SSR data.

3. Interactive Chapter 2 All-24-Notes Audit (Solving the "23/24 Notes" Blocker)
0 / 24 Notes CheckedOne of the most frequent completionist questions on the Steam forums is "chapter 2 23/24 notes? is it a bug or is there a note tucked away in a chase sequence?" Chapter 2 contains 24 collectible notes—not 23—and you do not need to delete your save file. Almost every player stuck at `23/24` missed the middle entry of the 3-part Adrenaline Junkie saga (#21 below). Check off your collected notes below to isolate the exact document you are missing.
Near the initial communications terminal desk.
On the workbench beside Dalton’s excavation notes.
Posted near the timed power-saver door switch.
Inside the catalog shelving room.
On the table inside the underground crew break room.
Resting near Stella’s field equipment.
Tucked along the side crate before the dark cavern drop.
First entry of the 3-part Adrenaline Junkie climber saga.
Beside the mechanical platform control lever.

Final note of the Adrenaline Junkie climber storyline.
On the crate leading toward the deeper digsite.
Final research report before finishing Level 2.
4. Lake Cave Stereo Country Song Puzzle & Plushie Pedestals (`ACH_StuffedAnimal`)
To unlock You Go Here (ACH_StuffedAnimal — 0.1% global unlock rate), you must locate every dinosaur stuffed animal (plushie) and place each one onto its matching stone pedestal. The most cryptic pedestal sequence occurs in the Level 2 Lake Cave immediately after the Gondola ride.
Play the Country Song & Wait for Completion
Right after passing through the padlocked gate following the Gondola segment, walk to the end of the wooden dock overlooking the subterranean lake. Interact with the portable stereo on the dock so it begins playing a country song. Do not leave immediately: once the song finishes playing in full, a ring of glowing blue swinging poles materializes around the central island in the lake.
Complete the Island Swing Course & Place Plushies
Chain your swings across the newly spawned blue poles around the center island to trigger the celebratory victory chime and ribbons at the finish platform. Make sure you also inspect the Stegosaurus Pedestal in this cavern and place each collected dinosaur plushie onto its corresponding species pedestal across the campaign to pop ACH_StuffedAnimal.
5. Three Fast Level 1 Interaction Achievements You Should Grab Early
Paleo Pal Review (ACH_PaleoPal)
Press the talk-box buttons in front of all four mascot displays (Benji, Alistair, Stephanie, and Dennis) inside the Level 1 museum before descending underground.
Kick the Rock (ACH_Rock)
Look down along the exterior/early path in Level 1 for the interactive rock prompt and kick it once to immediately pop this hidden achievement.
Globe-fetti (ACH_Globe)
Nearly three-quarters of players walk past the desk globe inside the Dalton's Dinos office/classroom without spinning it. Interact with the globe until the confetti celebration fires.
