Summercrab

Summercrab, also known as Springcrab, is an antagonist in Tyke and Sons Lumber Co. She is a crab animatronic modeled after crabs, who appears on Night 2 of the game.

Physical appearance
She is an olive green color. There is withering all over her body and organs inside of her. Her pincers have sharp, teeth-like spikes on their insides.

Gameplay
On Night 2, Summercrab will occasionally appear at the front door of the cabin. If the player sees her, they must flash their light constantly at her to make her go away. Failing to do so or ignoring her completely will result in a jumpscare.

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 crabs got one who goes by the name of Summercrab. She was originally made to find treasure, build houses and act as the crabs' companion. However, rumors surfaced that Summercrab was becoming sentient as she was seen sneaking out and trespassing into other creatures' homes. Even Chipper called the crabs out and called Summercrab hostile. After he disappeared, people assumed that she was responsible, which prompted the crabs to think of a way to destroy her. They lured her to a cliff and pushed her off.

She is called Springcrab because there were rumors of her appearing at springtime.
