How to Find the Last Hidden Treasure in the Sightless Passage in Pikmin 4

As you explore the Blossoming Arcadia in Pikmin 4, you’ll come across the Sightless Passage Cave. While using the Headlamp upgrade helps you see in the darkness, you may still get stumped by the last Treasure hidden here. Here’s how to find it.

Where do I find the last Treasure in the Sightless Passage in Pikmin 4?

If you don’t own the Treasure Gauge, you won’t have any idea where the last Treasure in the Sightless Passage is because it doesn’t appear on the map. Equally, you may still be confused even if you have the Treasure Gauge because it isn’t visible to the naked eye. Sending Oatchi to search for treasure might be the only way to find it.

Head to the northwest section of Sightless Passage, where you’ll find two Pyroclasmic Slooch enemies. You’ll know you’ve found the right ones if they look like fiery cone-shaped snails. Defeat them using Red Pikmin, as they’re resistant to fire and won’t take damage or, worse, die.

Once they’re down, throw out your Yellow Pikmin since they’re good diggers. If you don’t have any, use what you can, though they’ll be slower. They should run over to a certain spot and begin digging at the earth. Use Oatchi to pin down the exact spot by commanding him to look for treasure if you can’t find it.

Wait a few seconds, and they’ll pull a thermometer out of the ground, known as the Heat Sensor in Pikmin 4. You’ll need at least five Pikmin to carry it back. The Heat Sensor is worth 120 Sparklium.
