The Goblin Cave in The Forge (Roblox) is located in the Forgotten Kingdom area, directly next to the Goblin King.

Exact in‑game location

  • Travel to the Forgotten Kingdom using the portal.
  • Go to the Goblin King’s throne area (the Goblin Village/King’s room in Forgotten Kingdom).
  • The Goblin Cave entrance is the locked stone wall/gate immediately beside the Goblin King, usually described as being to the right of his throne.

You’ll recognize it as a stone gate with a big lock that doesn’t open until you’ve progressed the goblin questline.

How to unlock it (quick overview)

  • Complete the Goblin King quest or related Goblin Questline; the cave only opens once the final goblin quest submission is done.
  • This usually involves doing tasks for the Goblin King and/or obtaining the Goblin Cave Key via a secret quest.
  • After turning in the last quest step, the stone wall beside the king opens, revealing the Goblin Cave.

Inside, you’ll find lots of slimes and rare crystal nodes that can drop Epic and Legendary ores, plus objectives like Tomo’s Cat for side quests.

Simple step‑by‑step path

  1. Use the teleporter/portal to go to Forgotten Kingdom.
  1. Head toward the Goblin Village area where the Goblin King is located.
  1. Stand in front of his throne and look to the side (typically to the right) for the locked stone gate in the wall. That gate is the Goblin Cave entrance.
