According to Pixar’s Monsters, Inc. production notes, how many hairs cover Sulley’s body?

According to production information for Pixar’s Monsters, Inc., Sulley’s body is covered with 2,320,413 individually rendered hairs.

That unusually precise figure reflects the technical challenge of animating James P. Sullivan, whose design depends on a huge coat of blue fur. Each hair had to move convincingly as Sulley walked, ran, turned, fell, or interacted with other characters. The fur also needed to respond to lighting, creating the soft but dense appearance associated with the character.

Sulley’s fur was a major computer-animation achievement for Pixar in the early 2000s. The studio developed systems to handle large quantities of hair and prevent the strands from behaving like a solid surface. This helped make the character expressive while preserving his distinctive shaggy silhouette.

The number is often rounded in casual descriptions, but the production figure is 2,320,413. It refers to the individual hairs used for Sulley’s digital model, not the number of hairs visible in every frame.
