Peanuts is the name Boxey calls the daggit (dog) during a deleted scene from "Saga of a Star World".

The daggit is the exact same animal as Muffit, suggesting two things:

  1. Peanuts is the name of the actual dog who portrayed the original Muffit (not the drone daggit), meaning that the dialogue would later be redubbed by Noah Hathaway; or,
  2. Peanuts is the original name of Muffit, before it was changed later on.
