Who are the Terrible Lizards Paleo Pals? Meet Benji, Alistair, Stephanie, Dennis and Pterry, plus the four suits, the talk boxes and the achievement.
Terrible Lizards Paleo Pals: The Five Mascots Explained
The Paleo Pals are Dalton's Dinos' mascot lineup: Benji the Brontosaurus, Alistair the Allosaurus, Stephanie the Stegosaurus, Dennis the Dilophosaurus and Pterry the pterosaur. Four of them appear as full mascot suits in the museum and backstage storage. Pterry exists mainly in the park's branding and voice cast. Together they are the friendly face of a park that is trying very hard to eat you.
This page lists each mascot, explains where the suits appear, covers the four talk boxes needed for the "Paleo Pal Review" achievement and separates the mascots from the creatures they are named after. It contains light spoilers for the museum and the ending.

The Paleo Pals at a glance
| Mascot | Species | Role in the park | Where you see them |
|---|---|---|---|
| Benji | Brontosaurus | The friendly giant | Museum display, storage, talk box |
| Alistair | Allosaurus | The cool one | Museum display, storage, talk box |
| Stephanie | Stegosaurus | The gentle plant-eater | Museum display, storage, talk box |
| Dennis | Dilophosaurus | The odd one out | Museum, storage, arcade, talk box |
| Pterry | Pterosaur | The know-it-all showman | Branding, signage, voice cast |
The first four are the suits. Pterry is the outlier: a fifth mascot who belongs to the same lineup but does not have a wearable suit in the same display. That is why some guides say "four Paleo Pals" and others say "five." Both are describing the same lineup from different angles.
Benji the Brontosaurus
Benji is the big friendly one, which makes him the natural centerpiece of the museum. The Brontosaurus is the park's signature dinosaur: long neck, small head, impossible size. As a mascot, Benji is the character you would put on a lunchbox. As a suit, he is the one that makes the museum feel like a children's party that ended badly.
The species is also the source of one of the game's best running images. The real park has a Brontosaurus skeleton and a Brontosaurus animatronic; the mascot is the softened, commercial version of the same animal. When the game wants to remind you that the park sold safety and wonder, it puts Benji in the frame.
Alistair the Allosaurus
Alistair is the cool one, or at least the one the park's branding treats as cool. The Allosaurus is the park's main predator, so turning it into a mascot is either confident or reckless. The suit keeps the teeth but rounds off the threat, which is exactly what a mascot is for.
Alistair's talk box is one of the four needed for the achievement. The suit itself appears in the museum display and in storage. If you are sweeping Chapter 1 for the achievement, do not assume the museum is the only place to look; the storage room has its own lineup and its own prompts.
Stephanie the Stegosaurus
Stephanie is the gentle plant-eater, and the game uses her as the softest part of the lineup. The Stegosaurus is recognizable from the plates alone, which makes her the easiest mascot to read at a distance. In the museum, the suit is staged like a photo opportunity; backstage, it is just another costume waiting to be moved.
Her talk box is part of the same achievement set. The character is not a boss, a monster or a story-critical NPC. She is a piece of the park's design language, and that is why she matters: the park's cuteness is part of the horror.
Dennis the Dilophosaurus
Dennis is the one everyone remembers. The Dilophosaurus is the odd one out in the lineup, and the suit appears in the museum, in storage and in the arcade. The arcade appearance is the most unsettling: a mascot standing in a dark room full of cabinets, angled toward the player as if it has been waiting.
Dennis is also the only Paleo Pal who is more than a suit. The underground entity that cares for DJ uses the same name, and the game never explains the connection. The Dennis page separates the mascot from the creature and collects the evidence for the most popular theory.
The Dennis page and the ending explained page discuss the final chase and what happens to DJ. Read them after Chapter 4 if you want to avoid spoilers.
Pterry the pterosaur
Pterry is the fifth Paleo Pal and the one that breaks the dinosaur pattern. A pterosaur is not a dinosaur; it is a flying reptile from the same Mesozoic era. The park's lineup includes him anyway, because "Paleo Pals" is a brand, not a taxonomy.
Pterry is voiced by Greg Holgate, the musician known as The Stupendium. In the park's materials he is the know-it-all showman, the mascot who explains things. That makes him a natural fit for signage and recorded announcements, and it explains why he has more of a personality than a suit in a display case.
If you are looking for a Pterry suit to interact with, do not drive yourself crazy. The achievement uses the four dinosaur mascots' talk boxes. Pterry is part of the cast and the branding, not one of the four museum prompts.
The four talk boxes and Paleo Pal Review
"Paleo Pal Review" is the achievement most players miss on a first run. It requires interacting with all four Paleo Pal talk boxes in the museum during Chapter 1. The boxes belong to Benji, Alistair, Stephanie and Dennis. Each one gives a short piece of mascot dialogue, and the achievement pops when the fourth is triggered.
The museum is a one-way story section. If you leave without pressing all four prompts, you cannot walk back through the same instance; you need chapter select or a new run. The achievements page lists the completion rate and the other missable-looking achievements, and the Chapter 2 walkthrough picks up after the museum if you are already past it.
Benji, Alistair, Stephanie, Dennis. Four boxes, all in the museum, all before you leave Chapter 1. If the counter in your head says three, check the storage room again.
Are the Paleo Pals real dinosaurs?
No. They are mascots based on dinosaurs, and the game is deliberately loose with the science. Benji is a Brontosaurus, Alistair an Allosaurus, Stephanie a Stegosaurus and Dennis a Dilophosaurus. Pterry is a pterosaur, which is a flying reptile rather than a dinosaur. The all monsters page covers the actual creatures Jordan encounters, which are a different and much less merchandisable list.
The distinction matters for one reason: the game uses the mascots as the friendly version of the park's animals. The real Brontosaurus in the museum is a skeleton; the real Allosaurus in the caverns is a hunter. The mascots are what the park wanted people to see.
Merch and the in-game gift shop
The park's gift shop is full of Paleo Pals merchandise: T-shirts, toys and plushies on the shelves. None of it is interactive in a way that changes the story, but it is worth a look because it is the clearest statement of the park's business model. Dalton's Dinos sold cute dinosaurs to families, then built a real attraction underneath.
Outside the game, Terrible Lizards merchandise has been limited. A Terrible Lizards T-shirt was listed by Shark Robot for $24.95 with a pre-order window that closed on October 8, 2026. Availability after that window depends on the store, and there is no official plush line announced. If you see a "Paleo Pals plush" for sale, check whether it is fan-made before assuming it is licensed.
Why the mascots work
The Paleo Pals are not a minigame or a collectible set with a reward screen. They are set dressing that carries the game's tone. A mascot is a promise that the place is safe for children. Seeing one in a dark storage room, or standing in an arcade with its head tilted, breaks that promise without a single line of dialogue.
That is also why the achievement is easy to miss. The game does not put a marker over the talk boxes or tell you that the museum is your only chance. It trusts you to look around a children's attraction and wonder why the costumes are still there.
FAQ
How many Paleo Pals are there? Five: Benji, Alistair, Stephanie, Dennis and Pterry.
How many Paleo Pal suits are in the game? Four dinosaur suits: Benji, Alistair, Stephanie and Dennis. Pterry appears in branding and the voice cast rather than as a wearable suit in the museum display.
Who is the fifth Paleo Pal? Pterry the pterosaur, voiced by Greg Holgate.
Is Pterry a dinosaur? No. A pterosaur is a flying reptile, not a dinosaur.
Which mascots have talk boxes? Benji, Alistair, Stephanie and Dennis. Interact with all four in the museum for the Paleo Pal Review achievement.
Can you wear the mascot suits? The game does not give Jordan a wearable mascot suit. The suits are environmental props.
