# Terrible Lizards Monsters & Dinosaurs Guide: RJ Palmer Creatures, Paleo Pals, Story Lore & JT Music

## RJ Palmer Bioweapon Threat Matrix

Concept artist **RJ Palmer** (*Saurian*, *Detective Pikachu*) designed the mutated prehistoric predators inside Dalton's Dinos:

1. **Rexie (Black Goo Tyrannosaurus Rex)** — Chapters 1, 3, 4. High motion sight and stomp tremors; break line of sight behind concrete pillars and crouch during spotlight sweeps.
2. **Rascal the Raptor (Utahraptor Pack)** — Chapters 2, 3. Extreme acoustic sensitivity; toss rocks (`ACH_Rock`) at distant metal ducts to redirect patrols away from power switches.
3. **Trixie the Triceratops (Armored Ceratopsian)** — Chapters 2, 3. Narrow forward vision; sidestep her linear charge so she impacts structural columns or live junction boxes.
4. **Spike the Spino (Subterranean Spinosaurus)** — Chapter 2 (Lake Cave) & Chapter 4. Detects water ripples; stay on dry timber piers and trigger the dock boombox country song before swinging across.

## All 4 Paleo Pals Locations (`ACH_StuffedAnimal`)

1. **Rexie (`pal-rexie`, Ch. 1)**: Welcome Center Gift Shop checkout counter.
2. **Rascal (`pal-raptor`, Ch. 2)**: Maintenance Hub breakroom open locker.
3. **Trixie (`pal-trike`, Ch. 3)**: Sub-Level 2 Genetics Observation Lounge desk.
4. **Spike (`pal-spino`, Ch. 4)**: Hydro-Filtration Control Room console before the extraction lift.
