Things Better Left Unvisited:
Exactly What It Sounds Like, Mates.
It must be just sweet to be a goodbeast in the later novels.
Much like college fratboys, when anthropomorphic squirrels, hedgehogs and mice get together and are never scolded for anything wrong they do, and are instead praised for "defeating the foebeast" or "givin' those scummers what for", they will both attempt, and succeed, at getting away with anything. ANYTHING.
Anything short of murdering another of the spoiled fratboys.
In any novel after Pearls of Lutra, goodbeasts get away with anything in Redwall Abbey and get away with almost as much outside. Odd, considering how sometimes non-Abbeydwellers often threaten enemies that they are about to "take it outside" so they don't violate the Abbey's creed and charter.
The nominees this installment for winning the Biggest Redwall Douches That Were Never Punished Despite Heinous Crimes are...
Yoofus Lightpaw! The dormouse that loves to burglarize the Abbey a la Chickenhound style and goes completely unpunished!
That Unnamed Grumpy Watervole! He even managed to kill an ABBEY SISTER and didn't even get tracked down by the Abbeybeasts! A freakin' random weasel had to do it!
That utterly despicable Gray One! Got his tribe thirsty for the blood of the main heroes because of a swindle he himself committed!
Triggut Frap! Owned slaves! Tortured beasts! Not even a kick in the teeth!
Aggril (the Poisoner)! Poisoned the main characters after coaxing them into a state of trust, then planning to murder them! Except Boldred showed up and whisked the heroes away, but Aggril never got punished!
Blodd Apis, Evil Master of the Bees Who Likes To Torture Random Travelers! Except that she messed up and got herself killed, but the heroes all were sorry anyway for some reason!
And...Pakatugg! The squirrel which bullied the main character of Mariel of Redwall, even attempting to cripple her and leave her for dead, and magically became a hero right before he died! Also, he was randomly a hedgehog for two sentences...
Due to having been killed to death and getting poetic justice done unto them, Skan, Fenno, Druwp, and Tugga Bruster have been disqualified from the running. You know the nominees, and you probably don't love 'em! They lie, they cheat, they steal, they murder, and they sell out their friends. Have you noticed that the only bad "goodbeasts" are squirrels, hedgehogs, shrews or voles? More of that goodbeast-on-goodbeast racism that we all love!
And a bunch of the badgers are borderline bad, with just a smidgeon of demanding dictator.
Welllll... I would go ahead and count both Folgrim, the otter that likes to murder minorities and eat their flesh by choice but doesn't have to because of a traumatic event that may not have even happened and had nothing to do with said minorities, and that freakin' Zaran the Black. I know that one is supposed to be a good guy in Doomwyte, but come on! Kill your enemy (who isn't even really an enemy, more of an aloof, slightly crazy predator) by collapsing a cavern and letting them suffocate just because it's convenient? Why you gotta be all torturey? Matthias took out an adder just as dangerous, gigantic, and evil with a sword in close quarters. Just one swing, no more ouch. Also no more snake named after the Demon of Lust.
Freud, anyone?
And don't forget the one evil mouse! Nimbalo's father, who despite child abusing his son into being a bloodthirsty scamp is avenged righteously anyways. If a rat kills you, no matter how much of an asshat you were before, you must get justice. 'Cuz rats are worse than abusive fathers. Yep. More racism.
More may follow. If you like, you may leave an as-of-yet unanswered bit of unusual Redwall yore as a suggestion, but it is more than likely I'll cover the grand majority of oddness and unmentioned unmentionableness.
