No-Eyed Deer are passive, seasonal Mobs exclusive to Don't Starve Together, introduced in A New Reign. No-Eyed Deer spawn near the beginning of Autumn in Deciduous Forests or Mosaic Biomes and are always found in groups of 6 to 9.
They are considered innocent creatures, and killing one adds 4 points to the player's naughtiness level, which can cause Krampus to appear.
No-Eyed Deer will spawn 3–5 days into Autumn. They will not spawn on craftable Turfs, Savanna Turf, or Marsh Turf. They will always spawn as a group away from all players. The herd always stays together and all animals move exactly in the same direction.
As Winter starts the No-Eyed Deer will start migrating, growing their antlers after about 1 Day. If the No-Eyed Deer collides with an object such as a Tree the antler will break off. Within 2 days before or after the end of Winter, No-Eyed Deer will despawn unless they are within 1.5 screens (7.5 Pitchfork tiles) of at least 10 player Structures or Walls.
No-Eyed Deer will not run away from the player if approached, but will be startled. If attacked, they will flee.
- The name "No-Eyed Deer" can be interpreted as a pun on the phrases "doe-eyed" and "no idea". It could also be a reference to the fable, The One-Eyed Deer.
- No-Eyed Deer were added in the Herd Mentality update. Before the Winter's Feast update, they used the same sounds as Volt Goats and were neutral, attacking players in groups similar to Beefalo.
- The functional versions of the collared No-Eyed Deer were first shown on Rhymes with Play #116 and later released as the Gem Deer.
- The Antlered Deer's aesthetic is a possible reference to the popular 1966 Television special How The Grinch Stole Christmas.
