Worm Food is a boss-summoning item used to summon the Eater of Worlds. It can be used at any time of day, but can only be used inside The Corruption.
- Although the Crimson is equivalent to the Corruption, using Worm Food in the Crimson will not do anything. The Brain of Cthulhu substitutes the Eater of Worlds in the Crimson.
- It is however still possible to summon the Eater of Worlds in a world that spawned Crimson by artificially creating a Corruption biome (with Corruption-related blocks from another world), and then use the Worm Food within that.
