Inedible As any Slugcat


As any Slugcat: Farm Arrays

Rain Deer are tall, passive creatures found exclusively within Farm Arrays. They serve as the primary method of crossing the large fields of Worm Grass found throughout the region.


Rain Deer have large bodies with an oval head, two yellow eyes, a set of antlers, and four long legs. Their legs are thinner and generally lighter in shade at the tips and have four distinct joints. The underbelly of the Rain Deer's body has several hanging appendages of varying lengths. Similar appendages may also be seen on the antlers, although much thinner and shorter.



Changing direction when a Spore Puff is thrown

The player can grab and ride on a Rain Deer's antlers by pressing . The 3 simplest ways of getting a hold of them are:

  • Getting onto a Rain Deer's back while they are sitting down. When attracted by a thrown Spore Puff, Rain Deer often sit down near the spot it was thrown, providing an opportunity to grab their antlers. Though unreliable, waiting for a Rain Deer to sit down by themself also works.
  • Dropping a Spore Puff for the Rain Deer to eat. While eating Spore Puffs off of the ground, Rain Deer bow their heads in a way that makes their antlers easily accessible from the front. There is a short window that the Slugcat can regrab the Spore Puff while also boarding the antlers; this does, however, require quick reflexes.
  • Crouching down while in view of the Rain Deer. In response, they bow, giving the opportunity to jump onto their antlers.

While holding on, the player can wiggle their controls back and forth to prompt the Rain Deer to either begin moving or change direction if already in motion.

Abilities & Behavior

Moving across Worm Grass with the Slugcat on its back

Rain Deer slowly wander across rooms and ignore other creatures. Sometimes Rain Deer may stop moving in front of an obstacle before continuing to walk with a small burst of speed. Upon reaching the end of a room, they may choose to sit down, hiding their legs beneath their body. They behave a bit differently when ridden, often stopping at potential room exits, giving Slugcat time to get off their antlers. While they can be killed by Worm Grass if stunned, they usually escape easily if grabbed by it. When the rain comes, Rain Deer leave by moving out of bounds.


Rain Deer are attracted to Spore Puffs. When one is thrown, nearby Rain Deer emit a loud shriek before moving toward the spot where it was thrown. If they find one on the ground, they bow down in an attempt to eat it.


Rain Deer are affected by the dominance trait; ones with less dominance bow down to those with more dominance, letting them pass.

Variants & Attributes

Rain Deer's antlers vary in shape and length, the latter of which is determined by the dominance trait. The appendages that hang from their bodies and antlers vary in amount, length, position and thickness.


A Rain Deer attempting to shake the Slugcat off.
  • Decorated skulls of Rain Deer can be found at Scavenger Tolls.
  • If a Rain Deer is about to move out of bounds while ridden, they begin shaking violently back and forth.
    • This is likely an attempt to get Slugcat off of their antlers.
  • Rain Deer have a reputation system that can be viewed with dev tools, but is ultimately unused, as their behavior is identical regardless of reputation level.
    • While there are no in-game ways to increase it, reputation can be decreased by killing Rain Deer.
  • Hitting Rain Deer with Spears pushes them forward.
    • This allows for a strategy sometimes used in speedruns as the Hunter, where 2 Spears are repeatedly thrown at a Rain Deer while they are being ridden, providing a massive speed boost.
  • A Spear stuck in a Rain Deer automatically falls out after a second.[v1.9 Remix only]
  • The development of Rain Deer as documented in the dev log.
    • In this log, Dali's long-legged elephants are attributed as inspiration for Rain Deer.
  • It is possible to ride a Rain Deer as ✔️DLC Saint while grappled onto the body of another Rain Deer. This prevents the grappled Rain Deer from moving away from the Rain Deer that Saint is riding, and pulls it along when Saint's Rain Deer moves.
  • Riding a Rain Deer in ✔️DLC Saint's campaign has a strong warming effect.
  • Rain Deer are prone to bugs in their AI, either standing completely still, moving in unconventional manners, or going in wrong directions.
    • This can result in the player either getting stuck or being forced to attempt traversal through the Worm Grass itself.
  • Rain Deer are coded to be afraid of Giant Jellyfish, despite the fact that they cannot interact in normal gameplay.
  • Rain Deer's legs are referred to as "tentacles" in the game's code.
  • If Slugcat slides under a Rain Deer that is sitting, they gain momentum due to the physics interactions of the Rain Deer's mass.
