In the 2006 animated movie "Monster House," it is revealed that the titular house is alive and composed of bones. The reason why the house is made up of bones is never explained explicitly, but it is hinted to be a result of the house being built on top of a large grave, or a burial ground.

The film portrays the bones as a source of the house's power, with the house's eyes, mouth, and spine being the key points of its anatomy. The bones themselves are also depicted as being highly resilient, as they are able to withstand direct impact and other forms of damage without breaking.

Overall, Monster House bones are a integral aspect of the film's plot and serve to create an eerie and unsettling atmosphere throughout.
