Seabilly

Seabilly, also known as Seabill.exe, is one of the animatronic robots built by Seabob.

Physical appearance
Seabilly seems to be completely torn up with only his left arm, bowtie and upper face slightly undamaged, as one of of the eyes seem to have popped out of it’s area.

Gameplay
From Night 3 onwards, the player will occasionally hear Seabilly outside the cabin. When the player hears him, it means he is going to appear at the front door. There is a big delay between when he's heard and when he shows up, so the player has time to check for the other animatronics first. To defend against Seabilly, the player must stay in the middle of the living room and turn off the lights. Then, when Seabilly walks up to the door, he won't see them and leave.

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.

This was caused by an employee, who went rogue and tore Seabilly apart because of the stories they had heard about Seabob animatronics going around and infiltrating resident’s homes.

The employees got one who goes by the name of Seabilly. He was originally made as an entertainer for workers at Seabill IndustriesTM. But as the rumours about Killtimber and Summercrab were spread, one of the employees went crazy and torn Seabilly apart. After that Seabilly disappeared.
