Secret Tomb
Catch Bugs Secret Tomb
The Secret Tomb is a hidden area beneath Dune Burrow. It houses Anpu, who sells the Bone Net for 200,000,000 cash — the luck net that defines mid-to-late game hunting.
Unlocking the tomb requires carrying three specific bugs simultaneously. This guide walks the full route in the most efficient collection order.
Tomb requirements
You must carry all three key bugs in your active inventory at the same time — not in the vivarium, not sold.
The three key bugs
- Crescent Wing Butterfly — Moon Hollow, after 6:30 PM (night cycle).
- Wasp Moth — Deeproot Caves (bring a light lure).
- Spiny Harvestman — Dune Burrow, patrol burrow entrances at dusk.
Tomb entrance route
With all three bugs in inventory, go to Dune Burrow and walk into the rocky tunnel between the Potion Traders and the waterfall. The hidden entrance opens the Secret Tomb.
Tomb rewards
Inside, talk to Anpu to purchase the Bone Net (200,000,000 cash). The tomb also spawns Undead Scorpion and Thousand Scorpion — exotic bugs for your vivarium.
