Secret Tomb Walkthrough

The Secret Tomb is the biggest progression gate in Catch Bugs. This walkthrough orders key collection to minimize travel time and explains exactly where the entrance is.

Preparation checklist

Have Royal Net, 200M cash (or close), vivarium producing income, and empty inventory slots for three bugs.

Optimal key collection order

  1. Crescent Wing Butterfly — Moon Hollow, night (6:30 PM+). Slot in vivarium until tomb run.
  2. Wasp Moth — Deeproot Caves with light lure.
  3. Spiny Harvestman — Dune Burrow at dusk.

Finding the entrance

Remove all three bugs from vivarium into inventory. In Dune Burrow, walk into the rocky tunnel between Potion Traders and the waterfall.

Meeting Anpu

Talk to Anpu inside the tomb. Purchase the Bone Net for 200,000,000 cash. Hunt Undead Scorpion and Thousand Scorpion while inside.
