Who Killed the Deer in 99 Nights in the Forest?
The answer to this burning question has been confirmed through extensive investigation and community research: The Bat, a mysterious new entity with pink wings, is responsible for attacking and severely injuring the deer. This winged creature represents the first monster in 99 Nights in the Forest history to attack another monster entity, marking a significant shift in the game’s lore and dynamics.
The Attack: What Really Happened
According to the update’s opening cutscene, the deer was peacefully roaming the Forest biome when it was suddenly ambushed from above. The attack was swift and brutal – the Bat creature swooped down with incredible speed, catching the deer completely off guard. Players only catch glimpses of bright pink bat wings flashing across the screen before the deer collapses near the campfire, severely wounded.
This attack wasn’t random – it appears to be part of a larger power struggle for control of the Forest biome. Just as the Ram dominates the Volcanic biome and the Owl rules certain areas, the Bat seems to be challenging the deer’s territory and supremacy in the forest.
The Deer’s Injuries: A Closer Look
The severity of the deer’s injuries tells us just how powerful this new Bat creature really is. When you first encounter the injured deer, you’ll notice these specific wounds:
Visible Injuries:
- One antler completely ripped off – showing tremendous force
- Second antler severely cracked – indicating multiple powerful strikes
- Broken leg twisted at unnatural angle – suggesting the deer was thrown or slammed
- Deep claw-like wounds across the body – matching the Bat’s known weaponry
- Weak movement and heavy breathing – indicating critical condition
These injuries couldn’t have been caused by ordinary forest creatures. The combination of aerial attack patterns, claw wounds, and the sheer force required to damage the deer’s antlers points directly to a powerful flying predator – exactly what we know about the Bat.
All Clues Pointing to The Bat (July 2026)
Throughout the investigation, multiple clues have emerged that confirm The Bat’s identity as the attacker:
Clue 1: The Wing Sighting
The opening cutscene clearly shows pink bat wings attached to the attacker. These wings match the description and promotional art of The Bat entity that developers have been teasing.
Clue 2: Purple Fur Evidence
When helping the deer recover, purple fur tufts appear nearby. These match the fur color associated with The Bat in promotional materials and cave sightings.
Clue 3: Cave Dwelling Behavior
The trail leads to a massive cave much larger than standard game caves. This cave-dwelling behavior is typical of bat-like creatures and matches The Bat’s described habitat preferences.
Clue 4: Distinctive Cry
The creature’s scream from within the cave is unlike any other in the game – not matching wolves, cultists, or other forest beasts. This unique vocalization suggests a new type of entity.
Clue 5: Wing Confirmation
During the final confrontation, The Bat briefly extends its wing from the cave entrance, confirming the same pink bat wing seen in the attack cutscene.
The Complete Quest to Save the Deer
Saving the deer isn’t just about healing its wounds – it’s an epic storyline that reveals the deeper conflict between forest entities. Here’s the complete step-by-step walkthrough:
Step 1: Locate the Injured Deer
When you start a new game session after the November 15 update, you’ll find the deer lying on a patch of damaged ground east of the campfire. The deer is in critical condition and cannot move on its own.
Pro Tip: The deer’s location can vary slightly between playthroughs, but it’s always relatively close to the starting campfire area. Upgrade your campfire to level 2 to make the deer spawn more reliably.
Step 2: Heal the Injuries
The deer requires immediate medical attention. You’ll need:
- 2 bandages (one for the broken antler, one for the twisted leg)
- Medic class recommended for easier access to healing items
How to get bandages:
- Check the Clinic building
- Fish in bone lakes (unlimited source)
- Search inside various structures
- Visit the Tool Workshop
- Use Medic or Supporter class bonuses
Apply the bandages directly to the specified injuries. This will wake the deer up, but it will still be weak and unable to stand.
Step 3: Feed the Deer
The deer needs substantial nutrition to recover its strength. You’ll need to provide:
- 10-25 pieces of steak or meat (from rabbits, wolves, or other animals)
- Alternative food sources: carrots, soup, or other nourishing items
Each piece of food gradually heals the deer. Watch as the deer slowly regains strength, eventually sitting upright and then attempting to stand.
Step 4: Defend the Deer
As the deer recovers, it becomes vulnerable to other forest predators. Be prepared for:
- 2 Alpha Wolves spawning from opposite directions
- Immediate attacks on the weakened deer
- Protection requirement – you must defeat both wolves quickly
Strategy: Use hit-and-run tactics, focusing on one wolf at a time. The deer cannot defend itself in this state, so you’re its only protection.
Step 5: Give the Purple Fur Tuft
Once the deer is strong enough, Purple Fur Tufts will appear nearby. These are crucial clues:
- Collect the Purple Fur Tuft near the deer
- Give it to the deer to trigger the tracking phase
- Follow the deer as it picks up the scent and begins tracking the attacker
The deer’s behavior changes dramatically here – it becomes focused and determined, ready for revenge.
Step 6: Follow to the Hidden Cave
The deer will lead you on a path through the forest to a massive cave. This cave is:
- Much larger than standard rescue caves
- Contains a legendary chest with valuable rewards
- Has a dark pit area where The Bat can hide
Exploration Tip: Search the cave thoroughly before proceeding with the confrontation. The legendary chest often contains rare items that will help you in future encounters.
Step 7: The Final Confrontation
Inside the cave, the moment of truth arrives:
- The Bat screams from the darkness within
- The deer’s eyes turn red as it enters “hungry mode”
- A brief but intense battle occurs
- The Bat attempts to escape but is pulled back by the deer
The confrontation is quick but decisive. The deer, empowered by your help and its rage, defeats The Bat in a dramatic display of strength.
What Happens After the Fight?
The resolution of this quest brings significant changes to your gameplay experience:
The Deer Becomes Your Ally
Once victorious, the deer remembers your kindness and help. It now becomes an active ally during cultist raids:
How the deer helps:
- Aggressively enters the battlefield in hungry mode
- Kills cultists one by one with powerful attacks
- Protects the campfire by scaring away threats
- Guarantees full raid protection when present
This is the only time the deer fully enters the light and fights alongside players, making it an incredibly valuable ally.
Long-term Benefits
Having the deer as an ally provides:
- Automatic cultist defense during raids
- Reduced need for manual defense during attacks
- Strategic advantage in later game stages
- Story progression for future updates
