Synopsis
Harry Mudd is once again apprehended and incarcerated by the U.S.S. Enterprise crew, after trying to sell love crystals. Mudd abducts Nurse Chapel and briefly escapes to a rocky planet in a stolen Enterprise Heavy shuttlecraft, but he is recaptured and sentenced to an indefinite period in rehabilitation therapy for violations of the Federation pharmaceutical code, including fraud, illegal drug manufacturing, swindling, and transport of a dangerous life-form (a Rigellian hypnoid).

Notes:

• This episode's writer Stephen Kandel wrote another animated STAR TREK episode "The Jihad". Kandel also wrote the two Harry Mudd episodes of the Original STAR TREK series, "Mudd's Women" and "I, Mudd" to which this episode was a sequel.
• Actor Roger Carmel reprised his role of Harry Mudd by providing the voice of the animated Harry Mudd.
• There is a page in this site devoted to the Heavy Shuttlecraft used by Harry Mudd and Nurse Chapel in this episode.
• There was a visual error in this episode: one scene showed Nurse Chapel wearing a uniform with a black collar.
• Another visual error in this episode showed Spock with his insignia on the wrong side of his tunic.
• This episode had a very large role for Nurse Chapel, who usually had very little to do in both the original and animated series.
• A VHS video tape containing "Mudd's Passion" and "One of Our planets Is Missing" is available for purchase from amazon.com, the online bookseller.
• "Mudd's Passion" was novelized by Alan Dean Foster in Star Trek Log Three published by Ballantine Books in January 1975. Also novelized in the book was "The Magicks of Megas-Tu" and "Once Upon a Planet".
