The events from the first season episodes "Cluny's Clowns", "The Visitor", and "A Favour Returned" never occurred in the original Redwall novel (Methuselah's death occurred directly after his encounter with Chickenhound). Furthermore, several Redwall novel events and chronologies were altered to allow for thirteen continuous narrative episodes.
The character of Sir Harry the Muse from season two was named after a lawyer friend of author Brian Jacques. The real-life Sir Harry wanted to be made a rat, but the author felt that - as a lawyer - he had been a rat long enough.
Although fans were anxious for a fourth season of this show (possibly covering either The Pearls of Lutra or Mossflower), the producers at Nelvana were unable to secure financial backing or any American broadcasters willing to finance the series. Season four could not revive.
According to Brian Jacques, the character of Basil Stag Hare was slightly based on and named after John Cleese's character of Basil Fawlty from the sitcom Fawlty Towers (1975).
According to author Brian Jacques, the various characters' modes of speech were based on dialects from the British Isles: Moles: West Country villages Otters: Liverpool dock workers Shrews: Liverpool dock workers (turned into a gypsy dialect in this show) Hares: RP English, based on old British Army and Royal Air Force officers Vermin: Combination of Cornish English (for pirates and corsairs) and Cockney.
