  • Most background characters have two models: one for their daytime color palette and another for their nighttime color palette (for example, Fred's palettes are labeled "001-DAY" and "001-NIGHT").
  • Several of the original incidental characters were removed from the model sheets after the third season. Their numbers are known from storyboards. Specifically, numbers 33, 35, 61, 62, 70, and 71 are known from the storyboards of "Christmas Who?."


These incidental model sheets were uploaded by Vincent Waller to his Twitter on February 8, 2018.
