What horrors will you unleash upon our world?

I sure hope no one opens it, or worse, corrupts it.

-Scrapbook Description

The Terrarium is an item exclusive to Don't Starve Together and introduced in the An Eye for An Eye update. It can be found in a Conspicuous Chest that randomly spawns in a Forest. It is used to summon the Eye of Terror boss, which is done by dropping it on the ground, touching it, and waiting until nightfall (or touching it at night).

It can be corrupted with a single Nightmare Fuel, which will cause the contained plant to take on a withered appearance (similar to the Crimson biome's trees in Terraria). If it is active at night, the Terrarium will instead summon the Twins of Terror.

If the Eye of Terror or Twins of Terror are defeated, or a night is skipped after summoning the Twins of Terror at least once, the Terrarium enters a dormant state. In this state, it cannot be touched to activate it, and thus cannot be used to summon the boss(es). This state lasts for 15 days with default world settings.

The Terrarium will sink in the water. However, it will return to the coast.

Upon entering the Caves, the Terrarium will be dropped at the players' feet.


  • When activated, it releases a gentle ringing closely matching the first few seconds of the Overworld Day track from Terraria.
  • The appearance of the Terrarium and the beam it fires resemble the Last Prism from Terraria.
