Castle Miner Z Wiki

A player observes numerous Space Goo found in a cave in an Alien Crash Site.

A player prepares to mine a block of Space Goo with their Bloodstone Pickaxe.

Space Goo is a block introduced in update 1.5 of CastleMiner Z. It uses the same texture as the Slime block of the original CastleMiner. It is found exclusively within alien crash sites, and is essential in the crafting of energy weapons. It can only be mined with a Bloodstone Pickaxe or Laser Sword.

Space Goo can also be used as an alternative light source as opposed to Torches or Lanterns.
