The Ceiling of the Krab Krusty is a sentient ceiling that "instructed" Spingebill on how to work at the Krab Krusty and how to make a Krabby Patty.
The ceiling has been alive for over 9000 years. Its first known endevor is putting together a training video for the Krab Krusty, in which the ceiling became good friends with Patrick and a quick opponent of Skodwarde. Later, he shot Michael De Santa out of the blue, which turned Trevor Philips against him.
Some say that the Ceiling is a ghost, as it is strange that a Ceiling can speak at all. Jonathan Irons believes that the Ceiling is a relic from a different time when nations were unique in their ability to solve the world's problems.
