Bosses: Kill, Survive, or Avoid

Ask a new player to name the bosses in 99 Nights in the Forest and you will get a list of things that cannot be killed. The Deer, the Owl, the Ram, the Bat — they are the monsters that actually end runs, so they get called bosses. But almost none of them have a health bar, and the ones that do are somewhere else entirely.

That split is the whole point of this page. The game has exactly two dedicated bosses you fight and kill, and a larger set of night monsters you survive instead. Mixing the two up costs you gems, keys and nights, because the counters are opposite: the killable bosses reward distance and ranged weapons, and the unkillable ones punish exactly that.

This page is the roster and the sort. Each monster has its own page for the full counter; here we do the classification nobody else does — who can be killed, who cannot, what each one is gated behind, and the answer to the question every player asks at some point: is there a boss on Night 99?

Friendly NPCs like the Fairy are the opposite case: no fight, one shop, one gate.

Quick Answer

Two killable bosses you can farm in any run, five monsters you can never kill, and two event bosses that only exist while their event is live.

The Rule Nobody States: Most Bosses Cannot Be Killed

rblxguide's own boss page draws the line for you in its headings: it lists the Deer, Owl, Cat, Ram and Bat under "Unkillable Entities (Not True Bosses)" and keeps a separate "Killable Bosses" ranking. Our own entity pages say the same thing one at a time — the Owl is "invulnerable while hostile", the Cat has "no published health value", the Bat "has no health", and the Deer cannot be killed by any means.

That is not a bug and it is not a hidden mechanic. It is the design. This game's monsters are mostly hazards with a script: each one asks a specific question, and the answer is a behaviour, not a weapon.

Note how the Cat and the Owl are direct opposites: one punishes stopping, the other punishes moving. That is why players who "learned the Deer" die to the Cat — there is no single pose that answers all five.

The Two Killable Bosses

The ones with a health bar are a different kind of encounter, and they are the only two where bringing the right weapon matters.

Two things make these different from every other "boss" in the game. First, they both block loot: the Cultist King's Antler is the only route to the Infernal Helmet, and the Frog King's chest is the only route to the Poison Spear. Second, both are gated by something you farm first — gems or keys — so neither is a fight you stumble into.

The Cultist King: The Only One You Summon

He is the one enemy in the game you have to pay to fight. Nothing else works: he "never appears at random", and the only trigger is placing one Cultist Gem on each of four altars in the Cultist King Base in the Volcanic Biome. The fourth gem spawns him immediately, so you want your health topped up and your position chosen before that last placement.

The economics come first, because the 4 gems are the whole cost. They come from cultist kills (the last cultist of a raid is the reliable dropper) and from sacrificing items to the Volcano; the full ledger is on our Cultist Gem page. Then the fight itself is a distance check: shoot him, do not swing at him, and use the doorway, a ladder, or lava. His pathfinding is simple enough that he walks into terrain, and he cannot climb.

There is also a persistent rumour attached to this boss: the Cultist King Mace. Most "all weapons" listicles say he drops it; the fandom wiki states plainly that the Mace is an admin-only item you cannot obtain in normal play. We side with the fandom and the two independent guides that agree with it, and we say so on his page. Do not spend four gems chasing a mace.

The Frog King: The Only One Behind a Farmed Gate

The Frog King is the opposite gate: nobody summons him, and everybody has to farm eight keys first. The Frog Keys come out of key-marked ponds across the map, one per pond, and the door inside the whirlpool only opens with all eight. There is no shortcut and no purchase.

He is also the only boss whose fight continues after it is over. On death he splits into 2 Purple Frogs, each of those into 2 Blue, each of those into 2 Green — so the kill spawns a cascade of smaller frogs. The arithmetic is on our Frog King page: two, then four, then eight, fourteen more frogs where one boss stood. Clear them before the next wave lands, or bring something with reach and area damage — this is the one fight in the game where a crowd weapon beats a big single-target one.

The Five Night Monsters You Cannot Kill

These are the entities new players call bosses and veteran players call weather. Each one replaces The Deer on the nights it is active, and each is biome-linked — Snow gives you the Owl, Jungle the Cat, Volcanic the Ram — so the roster you face is decided by which outer biome your run rolled.

• The Deer — the default. It cannot be killed, a flashlight only stuns it, and the fire is a hard boundary it will not cross. Stop moving; do not run.
• The Owl — the Snow replacement. Stand perfectly still when the eye icon goes red. Feathers only drop if it leaves peacefully; fighting it is how you lose.
• The Cat — the Jungle replacement, and the most dangerous of the five. It punishes standing still and kills with a pounce whose landing circle you have to leave early. Unlike the other four, it is answered by walls — the one defensive build any source credits against it.
• The Ram — the Volcanic replacement. Sidestep the charge; there is no reward for engaging it at all.
• The Bat — the Caverns one, the only unkillable that cannot reach your campfire. Break line of sight, because a flashlight does nothing to it either.

Only one of the five gives a reward for surviving it well: the Owl, and only if you never made it hostile. The rest are pure cost, which is the real difference between a night monster and a boss.

The Event Bosses

Two fights only exist while their event does, and both are the finale of a seasonal chain rather than a normal encounter.

Imposter Santa is the Christmas-event boss. He is behind the North Pole, which unlocks at Campfire Level 4, and behind a chore first: decorating twelve Christmas trees with lights before the workshop opens. Inside are three Candy Turrets you have to destroy (each needs a Ladder or Shovel to reach, and each pays out two Candy Canes), and then the boss himself, who summons more turrets mid-fight. Beating him powers the Present Machine and the Elf Shop.

The Alien Command Center is the Mothership-event boss — the target in the main room of the Alien Mothership, and the step that earns the Mutiny badge. Both of these are event-gated, so the schedule on our Update Log is what decides whether either is even reachable on a given day.

Night 99 Has No Final Boss

This is the question the whole page exists to answer, and the answer is no.

Night 99 is an ordinary survival night. New Web Play states it flatly — "there is no special boss or unique event" — and every source we found agrees. There is nothing scripted to fight, nothing that spawns because you reached the end, and no enemy that only exists on the last night. Our own How to Win page reaches the same conclusion from the win condition side: the true ending is a schedule you finish, not a boss you kill. All four children have to be home before the counter resolves — that is the win, not a fight.

If you have been saving gear "for the final boss", you have been saving it for nothing. Spend it on the Cultist King or the Frog King instead, because those are the only two fights in the game that pay out.

One dissenting note, recorded rather than adopted: a single non-English guide (GamerMovil) describes a Wendigo appearing on Night 99 in the no-rescue secret ending, where it devours the camp. No English source we found repeats it, and it describes a cutscene, not a fight. We list it under the disagreements below and do not publish it as a mechanic.

The class you pick for a boss is often a speed decision, and our Sprint Speed guide ranks the boosts behind it.

Which Class for Which Boss

The class pages were written one at a time, so this comparison exists nowhere. It matters because the same class that wins a party fight can be dead weight in a solo one.

The pattern is simple: single-target ranged damage beats the two killable bosses, and sustain beats a long fight. Crowd damage and traps are for the hordes in between, not for the boss at the end of them.

Class weapons are the other thing that decision buys, and our Scythe page covers the melee one that comes with a class.

Where Sources Disagree

Six places the record conflicts or is thinner than it looks. We keep them listed rather than resolved; this is the state of the sources as of 2026-10-08.

1. How many bosses are there? It depends on whether you count only killable fights. This page counts two dedicated bosses (Cultist King, Frog King) plus two event bosses. rblxguide counts three killable "bosses" by folding in the Cultist Stronghold Gauntlet — a three-floor clear that is not a single enemy. Our own Cultist Stronghold page treats it as a location, not a boss. Both readings are defensible; the number changes with the definition.
2. The Cultist King's health. The fandom wiki lists 1,150 HP and 50 damage. Our own page flags ~1,000 as a single-source estimate rather than a stat sheet. Any "how long to kill him" arithmetic depends on which number you use.
3. Is the Deer a boss? Our own Deer page calls it "the unkillable boss"; rblxguide files it under "Not True Bosses". Same creature, two labels — and the label is exactly the thing new players get wrong.
4. The Cultist King Mace. Most generic weapon lists say the boss drops it; the fandom wiki and two independent guides say it is admin-only and unobtainable. We publish the admin-only reading.
5. How many frogs does the Frog King make? Our own count is 14 more (2 + 4 + 8) on top of the King. rblxguide describes "15 frogs total across all phases", which counts the King himself in the sum. Same cascade, two totals.
6. A Night 99 boss. No English source has one. GamerMovil, a non-English guide, describes a Wendigo on Night 99 in the no-rescue ending. It is not corroborated anywhere and reads as a cutscene, not a boss, so we record it and do not use it.

Frequently Asked Questions

How many bosses are in 99 Nights in the Forest? Two you can kill in any run — the Cultist King and the Frog King — plus two event bosses (Imposter Santa, the Alien Command Center). The Deer, Owl, Cat, Ram and Bat are frequently called bosses but cannot be killed at all.

Is there a final boss on Night 99? No. Night 99 is an ordinary survival night. The ending is a condition — all four children home before the counter resolves — not a fight.

Can you kill the Deer, the Owl, the Cat, the Ram or the Bat? No. None of them has a published health value, and the untameable, no-drop tables match. Flashlights only stun the Deer, Owl and Ram briefly; against the Cat and the Bat they do nothing.

Which boss should I fight first? The Cultist King, if you have two or more players and a ranged weapon — his Antler unlocks the Infernal Helmet. Go solo only if you are a Vampire or have a strong ranged kit.

What is the hardest boss? By gate and by fight, the Frog King. Eight keys, a wave-based arena, and a death that spawns fourteen more frogs. The Cultist King is a distance check; the Frog King is an endurance one.

Does the Cultist King drop the Mace? We do not believe so. The fandom wiki states it is admin-only and unobtainable in normal play, and two independent guides agree. Farm him for the Antler, not the mace.

Do any of the night monsters drop loot? Only the Owl, and only if it leaves peacefully — 0–1 Feather. Every other unkillable drops nothing, no matter how well you survive it.
