The Petraptor is a friendly Mudraptor Pet that can be created by an Assistant with the "The Friends We Made" Talent.


The Petraptor is a friendly Mudraptor which is 70% the size of an adult Mudraptor. It's distinctly darker than typical Mudraptors and has deep purple colored flesh. Despite its age and size, the Petraptor is still a threat to Europan life.
The Petraptor can be spawned by giving Saline to a Petraptor Egg and waiting for it to grow. Interestingly, the Petraptor Egg must be placed on the ground in front of the Medical Fabricator that created it. It cannot be moved to another location without growing it first.


The Petraptor has two kinds of hidden behaviors that the crew needs to pay attention to: Hunger and Happiness.


Every Pet needs to eat to relinquish their Hunger, which increases by 0.03% every second (maximum hunger reached in 3333 seconds or roughly 1 hour). At 30% Hunger, Pets become hungry and the Hunger icon will appear above their head to notify the crew that they need feeding. The player can feed them by dropping an appropriate food item on the ground and the tamed Creature will approach and consume it immediately. It stops requiring food when Hunger is below 30%.

There are four Pet Food types that Pets can consume: type 1, type 2, type 3, and monster food. Corpses can be consumed by the Petraptor. Corpses will completely feed the Petraptor and provide 10 happiness. The Petraptor can only eat monster food, which satiates 50% Hunger and increases 5% Happiness.

Items that are classified as Monster Food include:

Due to the priority order of behaviors, the Petraptor will prefer to protect its owner over eating food. This can lead to unintentional pet deaths as a distraught owner tries to feed their pet, unknowingly being the reason the pet refuses to eat. To prevent this, ensure the owner is at least 2 meters from the pet during feeding times.


The Happiness is the state of Pets that ensures the occurrence of high quality item production.

The Petraptor's Happiness decreases by 0.016% every second (maximum duration of 6250 seconds or 104 minutes) and can be increased by being fed or played with. There is a 6 second cooldown before the player can play with it again.

When Happiness is high enough and Hunger is below 30%, the Happy icon will appear above its head. But if Happiness is low enough regardless of Hunger rate, the Sad icon will appear instead.


When well-fed (0-30% Hunger), the Petraptor will start producing some items at a specific rate, most commonly a pile of Poop. At 80% Happiness and beyond, there is a 30% chance it will lay a Mudraptor Egg, which can be deconstructed for materials or used to hatch either a Mudraptor or another Petraptor.

All produced items are dropped on the ground from the respective Pets, which can be harvested simply by picking them up.

Combat Strategies

If a player intends to fight a Petraptor in close quarters combat, it is recommended to use ranged weapons. As the Petraptor lacks armor, it is much less of a threat compared to an armored Mudraptor. The use of a Revolver, SMG, or Harpoon Gun can quickly neutralise an enemy Petraptor.

It is important to note that if all other options have been exhausted, a player can quickly kill a Petraptor using Raptor Bane Extract; a refined plant extract which is lethal to Mudraptors. It can be fired from a Syringe Gun, which allows the player to maintain a safe distance. If none of the above strategies are viable for the current situation, Petraptors can be killed using melee weapons such as the Crowbar or Boarding Axe, however this method is incredibly dangerous and not recommended in the early game.
