How to Get the Tadpole Vehicle in Subnautica 2: 2026 Guide

Learning how to get the tadpole vehicle in Subnautica 2 is essential for players looking to explore deeper biomes and progress through the story. Developed by Unknown Worlds, this sequel requires players to scan three tadpole fragments and construct a moonpool and vehicle fabricator to unlock the craft. Once built, the tadpole provides a mobile oxygen supply, allowing for safer traversal of dangerous environments, though players must still exit the vehicle to interact with objects or collect resources.

To secure your own tadpole, follow these steps:

1. Locate and scan three tadpole fragments in the game world.
2. Construct a moonpool at your base.
3. Build a vehicle fabricator on the edge of the moonpool.
4. Access the fabricator to craft the tadpole using the unlocked blueprint.

Where to Find Subnautica 2 Tadpole Fragments 2026

Finding the necessary blueprints is the first step in our In Game News guide for Subnautica 2. Fragments are scattered across the map, often near points of interest. You should prioritize searching the following locations:

• Near Ruby's black box, situated 350m northeast of your lifepod.
• 145m south of the lifepod, approximately 90m below the surface.
• Inside the Colonist Bunker, located 400m southwest of the lifepod at a depth of 88m.

Once you have scanned three of these fragments, the blueprint will automatically be added to your PDA. If you are struggling to find these, ensure you are checking the specific depth markers mentioned, as the fragments can be easily missed in the darker, more cluttered areas of the ocean floor.

Subnautica 2 Tadpole Vehicle Crafting Requirements 2026

After acquiring the blueprint, you must prepare your base for construction. You will need the Habitat Builder tool to place a moonpool and a vehicle fabricator. It is important to note that the vehicle fabricator must be placed on the edge of a moonpool. If you encounter issues during placement, ensure your moonpool is a full-sized structure. In some instances, a smaller moonpool may not support the fabricator properly; if this occurs, deconstruct the smaller unit and rebuild it in a larger room to ensure compatibility.

The tadpole serves as a vital tool for survival. While it does not make you invincible against the game's hostile leviathans, it provides a necessary buffer for oxygen management. Even at 250m below the surface, the vehicle allows you to maintain a full tank of air, which is a significant quality-of-life improvement compared to swimming manually. However, remember that you must leave the cockpit to perform scans or gather resources, leaving you vulnerable to the surrounding wildlife.

How to Get the Subnautica 2 Tadpole Pens Key Code

Progressing the story often requires reaching the tadpole pens, a restricted area that cannot be accessed without a specific key code. To obtain this, you must wait for your NoA (Network of Assistance) to ping you the location of Zip's black box. This item contains the necessary code to unlock the rear room of the structure.

Reaching this location is a high-level task. Before attempting to retrieve the code, ensure you have the following:

• A functional tadpole vehicle.
• The Rebreather upgrade to manage oxygen consumption.
• The heat tolerance adaptation to survive the environmental conditions near the cave.

Once you have the marker on your screen, head to the general vicinity. You will need to descend through a series of natural pathways. While there is no direct vertical drop to the marker, the environment is designed to guide you downward if you follow the natural spiral of the caves. Keep an eye out for the specific cave entrance indicated in your mission logs. The black box is hidden deep within these tunnels, and the tadpole is required to navigate the depths safely.
