Build your first Tadpole and keep it running

Fragment options, dock clearance and the vehicle recipe.

Early Access 1.2 · Buddy System Hotfix 1, September 3 amendment · Updated 2026-09-12

The short answer

Scan three Tadpoles, then prepare a Moonpool, Tadpole Dock and Vehicle Fabricator. Leave clear space beneath the base; the dock extends downward.

Before you start

  • A Scanner, oxygen upgrades and base crafting facilities.
  • A powered vehicle supplies oxygen, but its current depth rating still limits the route.

Start with the shallower fragment options

Check the wrecked Tadpole northwest of the Old Habitat, and the ravine around 280 m northeast of the Lifepod at a 75° bearing. A deeper fragment lies among colony wreckage by the abyssal-crater edge northeast of the Lifepod. Treat the third as a separate prepared dive.

Separate the dock from the vehicle budget

After installing the dock facilities, the Tadpole itself costs 2 Titanium Ingots, 1 Glass, 1 System Chip and 1 Power Cell. The Power Cell requires Strong Acid and Salt, so those materials are a separate preparation step.

Carry a spare Power Cell and a Repair Tool. Fit discovered modules through the top upgrade compartment; read each module’s stacking text rather than assuming duplicates work.

Apply the current oxygen and sharing rules

Hotfix 1 fixes oxygen replenishment for players attached to a Tadpole or Haul. Inventory sharing is blocked while riding a Tadpole. Stop in a suitable location and leave the vehicle before trying to trade.
