Kookoo

ATTACK Kills players holding an item when its clock hits the chosen number

REPRESENTS: Sins caused by Escapism[1] ALIASES Cuckoo Memory A clock that hates items

If two Kookoos were to count up to the same number and attack on the same number, then one of them would play its regular sound while the other plays an octave higher. (This happens when the Bloatware modifier is enabled.) Kookoo is one of the 5 entities so far that have been first released in the Test Branch. Kookoo represents the sins caused by escapism. This is because when it spawns, it forces the player to put their items away. However, if the player thought that they can just get away without doing so, they'll get punished for it. Kookoo also represents treachery. This is because the player deliberately breaks the PROMISE made to Kookoo by holding onto a material possession when Kookoo's hand reaches the indicated number. Kookoo also forces the player to temporarily betray their items in order to survive. This is also supported by the fact that Kookoo's death screen shows the message "FORGETTING SOMETHING" and "UN:FUL:F1L:L3D:PROM:1S3S" (unfulfilled promises) representing the player's continuous act of breaking promises and betrayal. Kookoo's document repeatedly shows the text "ERROR 408: PROMISE TIMEOUT". Error 408 or "408 Request Timeout" is an HTTP status code that means the server did not receive a complete request from the client (your browser) within the allocated time limit. The "Promise Timeout" instead of "Request Timeout" may show the significance of pacts rather than questions. Requests are only an obligation once the other party accepts it. However a promise is an immediate obligation on someone, possibly meaning that the player's promise to Kookoo is to not hold their items when Kookoo attacks and Kookoo's promise to the player is that if the player does not hold any item, Kookoo will not kill them, possibly testing betrayal and trust. This can be seen as a promise as the player has a forced vow on them. An Error 408 only happens when a request is not completed within the allocated time limit, which could explain why Kookoo works as a clock, givin

The "timeout" may refer to the player having to unequip their items, timing out on them temporarily The "timeout" may also refer to the promise itself being timed out (or not fulfilled, as when something is timed out, it generally means stopped or incomplete, just like the original Request Timeout that happens when a request is incomplete, showing the player's reluctance to comply with Kookoo's promise) During its prototype, Kookoo used Litany's body. It was translucent when counting and went opaque after finishing the timer. It also used Litany's death screen.[6] Kookoo and Dozer are Enemies you can choose in Nullscape, as part of their collab with Grace. Doombringer is also available as a Greater Curse. In Nullscape, Kookoo can appear on a pedestal to then be selected as a permanent Enemy on level 10 onwards. Kookoo used to spawn occasionally while using the cog trait, but this was changed in the SOUL OVER BODY update. This did not count as officialy unlocking Kookoo, and you could still get the modifier that spawns it (TICK TICK).

Trivia

Kookoo, along with Litany, were meant to be separate Dozer variants. Kookoo was originally going to be named "Memory", as shown as in the placeholder design. After that, the name "Cuckoo" was proposed however was denied by Roblox's filtering system.[2] The name "Kookoo" is inspired off the term "cuckoo clock" which makes sense considering its mechanic. This entity's spawn command is .Kookoo. Just like Litany, typing a variable number at the end such as ".Kookoo 5" will set Kookoo's number to five. Despite Kookoo's note saying 0-7, it is actually 0-12. 0 to 7 might mean that it's counting from 0 up to the given number, with it being up to 7 due to lack of space on the note. Kookoo was added "[because] we just wanted a third option for there to be a trio," as said by HexT, the same story as Litany. Design wise, the BSoD (Blue Screen of Death) was a big factor in Kookoo's creation. The end of Kookoo's jumpscare is a reference to error screens of old Windows computers, specifically Windows 95 and Windows 98. Kookoo's summoning command allows players to set its timer to any number accepted by Lua's tonumber function. Using this, we can find out that the countdown does not display any number above 99. Kookoo's countdown can actually go as high as the 32-bit integer limit, but it won't be displayed. If NaN or -NaN is typed after the command Kookoo will countdown infinitely without attacking If "inf" is typed after the command Kookoo will display a glitched number before infinitely counting up. Using a negative number in Kookoo's "countdown" argument will result in Kookoo showing a blank time, before instantly attacking. When Kookoo was being designed, the devs had accidentally realized the colors were actually just the inverted colors of Dozer.[3] Coincidentally, both entities have a similar emoji-reminiscent design. Kookoo's hand, as seen when pointing at the number, is actually slightly purplish. According to the developers, Kookoo actually has no eyes.[4]

Behavior

Kookoo will randomly appear on the player's screen in the form of a clock with an arm pointing towards it. The arm will have the word "REMEMBER" written on it and be pointing to a number on Kookoo's clock-face. This number can be any number between 3-12. The clock will begin counting up from 0 towards that number, constantly relocating itself on the screen with each tick. When it reaches that number, Kookoo will close its mouth, and players must not be holding any item or else Kookoo will kill them instantly. If a player is wearing SHAKE, Kookoo will break it, and begin counting twice as fast. If the player does not remove the broken SHAKE upon the re-strike, Kookoo will kill them.

On death, the player and their held item on death will be turned into a solid blue color (with the exception of Doombringer being white with blue patches) with an 'ERR' particle effect fading in and stretching before fading out, similar to Dozer's eye antics. On the victim's screen, Kookoo will rapidly duplicate, filling up the screen before the player's visuals blue-screen afterwards, killing them. Despite being able to see very minimally through cracks of the multiple blue-faced killer, the player cannot walk during this phase.

If the player dies before Kookoo finishes counting, the strike sound can still play during the death screen if counting finishes before the game attempts to retry or spectate, however pressing equipment keys (1 through 9) will not trigger the death sound of Kookoo, nor will it bluescreen the player as usual.

Once the player dies to Kookoo, the screen will turn blue and this text will appear:

Kookoo has a blue, circular head. He has no eyes, but instead has white crosses, but he sees perfectly well. His mouth is a white line, usually stretched into a wide smile. He wears a white shirt with a blue overcoat, blue trousers with classic men's shoes of the same color, and most often wears a blue hat with a white ribbon, but not always. When Kookoo is angry, a chaotic blue aura with vertical stripes appears around its head.
