Chefosaurus Rex is a deviant in Once Human. The world of Once Human is a ravaged post-apocalyptic wasteland where vicious Mutants roam. Mutants are entities corrupted by mysterious Stardust corruption. While many of them are enemies, some are friendly. Fortunately, Chefosaurus Rex is one of the friendly ones.

True to its name, Chefosaurus Rex is a chef, and if you encounter it in Sunbury, you'll understand why. In appearance, this Deviant looks like a person wearing a giant blue dinosaur costume. It has a cartoonishly big head with teeth and a long neck, standing upright on two feet.

You can take on this mission relatively early in the game. The recommended character level is 15. To start this mission, go to Meyer's Market and look for Lowe. You can find him near the table beside the teleporter. Interact with him, and he'll talk about a nearby dragon, thereby starting the "There's A Dragon Here" quest.

Begin the mission, and it will take you to Sunbury. You'll find Chefosaurus Rex cooking something in the shop kitchen. The deviant is frustrated and hungry. You can calm it down by offering some delicacies you've made. The Deviant will demand the following dishes:

  • A roasted fruit dish
  • A roasted meat dish
  • Steak Combo

Give it these dishes, and it will become available for capture.

The second method for obtaining Chefosaurus Rex is to farm the Secrument Silo PHI dungeon in Iron River. The recommended level for this dungeon is 25. Enter the dungeon and progress until you reach the distorted space area. Jump in and enter the Operation Theater.

The furniture in the OPT will start flying when you enter. Don't be alarmed; wait a moment. When everything settles, leave the room, and you'll reach a boss arena. Kill the umbrella-like main boss and its minions. Then, go through the mysterious void gate with a black frame and glowing entrance.

When you pass through the gate, you'll reach a room where you can potentially find the Chefosaurus Rex deviant. You may need to grind this dungeon several times to make it appear in this location.

Once you've successfully captured the Deviant, you can equip it in an isolated Securement Unit. When activated, it will run around your territory and boost your cooking speed. Amenities like the radio improve its mood.


That concludes our Chefosaurus Rex guide. We hope this information will help you obtain and utilize the cooking dragon more effectively.
