Killtimber

Killtimber, also known as Nightmare Chipper, is an antagonist in Tyke and Son’s Lumber Co. He is a beaver animatronic modeled after Chipper, who appears on Night 4 of the game.

Physical Appearance
Killtimber is a large brown beaver animatronic with blue overalls, who was left in the woods to rot by the beaver family. His eyes in illustrations of him appear blue, but in the game they are red. Killtimber's suit is currently damaged and withered away. He also has noticeable splashes of blood on different parts of his body, such as his muzzle, for example. Many parts of his exoskeleton, including something that looks like the saw of a Phantom Chipomat can be seen.

Gameplay
Killtimber will appear at the front door, therefore, the player must flash their light rapidly at him until he'll disappear. If the player doesn't pay attention to the door, then Killtimber will come inside and attack the player. Later he will head upstairs into Mike's bedroom and a message will appear, saying "Something has come inside, don't stay in the same room with it too long!". The player must be very quick when getting the batteries from the bedroom, if the player stays in the bedroom with Killtimber for too long, then he will jumpscare the player, ending the night.

Once the player's sleep assurance is full, Killtimber will still be in the bedroom preventing the player from ending the night. To end the night, the player has to flash him with the flashlight, leave the bedroom and re-enter the bedroom with Killtimber absent in it. Taking too long to re-enter the room will cause Killtimber to return to the bedroom.

Lore
Prior to the events of this game, a robot industry was growing rapidly. Almost all the inhabitants of this island got a machine to perform their tasks. Seabob built special robots by himself, which he gave to his closest friends.

The beavers got one who goes by the name of Killtimber. He was originally made to chop trees and make lumber. However, Kiltimber was seen creeping around the house, accidently scaring the beaver family. After some time Chipper has had enough: he took away Killtimber's axe and told him to find the "Golden Tree" which is not a real thing so Killtimber was destined to wander around the forest forever.

Voicelines
"You took her away from me!"

"Home Sweet Home... *Villainous Chuckle*"

"I despise you..."

Killtimber's monologue during secret ending
"'You know, ever since I've been working for the beavers, which has been a long time, I can't help but remember the first time I laid my eyes on her. Summercrab, she's hands down gorgeous with her amazing smile, dem big black eyes and those pincers... Oh my, those pincers! A beaver's ideal woman was mine right as we met at the bar. What a sight! Though some don't understand the affection robots can feel for one another, though despite all that, it didn't matter. We were two robots whose hearts had a pulling force, the feeling of electricity. But as time went by, the beaver family, my family, became suspicious about me. They noticed my trips to the beach, sometimes at night. I never thought they would eventually toss me out, disconnect themselves from me, or even betray me with their fabricated lie about that so called 'Golden Tree'. They left me in the woods to rot for the rest of my time alive. Those beavers just wanted wood. Just wood. No affection at all! Summercrab is too gorgeous to be there... They'll eventually treat her badly and then throw her out too! I can't wait for that possibility. I must save her. They are the monsters! Not me! I have to make sure they never forget about that... ...no matter what my programming makes me do...'"
