The Cthulhu Project Addon (1.19) is a small Minecraft bedrock edition addon that introduces various monsters from the Lovecraft Universe into Minecraft, with new bosses, new structures, new blocks, and new items. This addon is compatible with survival mode!



Skull Altar

  • The Skull Altar is a rare structure in the plains, in order to summon the Dimensional Shambler, you must click on the Skull Rune with a Cursed Voodoo Doll, obtained rarely from killing Gugs.


You’ve angered the gods and now their monsters are out to get you too!


  • The Mi-Go is an alien, wasp-like flying mob that lives in the end, they’re rare and swoop down from high areas to attack their targets. They are hard to hit but drop a randomly enchanted book on death.


  • The Sperid is a two-legged, zombie-like fish person.
  • They’re pretty fast and will drop a random fish on death.
  • They spawn day AND night in swamps, making them an annoying threat.


  • The Gug is an intimidating, hulking mutant with 3 mouths, one on each hand, and one to make up its head.
  • The Gug spawns in Soul sand valleys and drops rotten flesh.
  • It has a rare drop, that being the Cursed Voodoo Doll.



  • The Shambler is the first boss, it spawns in the rare skull altars, requiring a Cursed Voodoo Doll to summon.
  • The Shambler is fast, does massive damage, and roars, summoning minion Sperids to aid it in combat.
  • Upon death, it will drop a Shambled Sapphire, which will have use in spawning Boss two.


  • Cthulhu is the final boss (for now) in this addon but has a special spawn method.
  • Use the below-crafting recipe to craft a Ritual Box, once placed, you can interact with it to summon Cthulhu, along with making the Ritual Box unusable.

  • Cthulhu will fly around, make the sky cloudy and rainy, and fire very fast shulker bullets that deal high damage.
  • Beating Cthulhu will make him drop either 1-25 Emeralds, or the Great Old Blade, a very powerful sword, or both!
