This troper actually directly asked the author about that; he claimed it was a coincidence and he did not learn about Cluny Abbey until after he wrote the book.
This other troper who read said Q&A on "Ask Brian" adds that Brian thought the coincidence was creepy.
You know that sword that Martin spent pretty much all of Martin the Warrior trying to get back from Badrang? Read the series in chronological order and you'll realize that this was the same sword that was broken in the beginning of Mossflower, which makes the ending even worse.
Taggerung gives us Madd, a mad old squirrel who suffered a serious head wound when vermin attacked and killed her family. Later on we meet Fwirl, a young squirrel who was orphaned when vermin attacked and killed her family. She recalls coming out of hiding and sitting near her mother, lying very still with a deep head wound. Hmmm...
Marlfox is told in three acts, not three books like all the other Redwall novels. Apparently Florian tweaked the narrative a bit so he and all the Noonvale Companions could act out the entire book as a play. To spare you further confusion, we'll just say Jacques was Leaning on the Fourth Wall.
At the end of Loamhedge, Bragoon and Saro commit a Heroic Sacrifice. However, if you look back on it, you'll notice it's also a Senseless Sacrifice. If Horty, Springald and Fenna hadn't left the Abbey in the first place, Bragoon and Saro probably wouldn't have had to sacrifice themselves. And to make it worse, the only reason why either of them went to Loamhedge was to find something to make Martha walk again, but Martha ends up walking on her own when Raga Bol's forces invade Redwall, meaning that Bragoon and Saro could've lived if they just stayed at the Abbey.
Not really. It was explained in series that, had Bragoon and Sarobando been at the Abbey for the coming of Raga Bol (or indeed for Baddred's crew before that), then the entire situation would not have been nearly as bad as it was, never leading to that critical moment where Martha either needed to walk or Lonna would die. It's still a rather twisted system (Given her characterization, Martha would have gladly chosen to remain chair-bound the rest of her life if she knew they were going to die to fix her), but it at least makes sense.
No, it doesn't. If all this is true, then that means that Martin the Warrior's spirit knew that Raga Bol and Badredd would attack Redwall. Which means he intentionally had Bragoon and Saro sent away just so they could invade Redwall. Which means Martin knew that Bragoon and Saro were probably going on a Suicide Mission (which turned out to be true). Which means that if they had just stayed at Redwall, Junty the Cellarhog and several other Redwallers might have lived and Raga Bol and Badredd would not have invaded Redwall, or at the very least, got so far inside Redwall. Overall, the lives of dozens of Redwallers apparently isn't as important as making a single wheelchair-bound hare magically walk again due to an intense amount of stress and adrenaline. Do you see how fucked up that is?
You're trying to say that you know possible outcomes better that a character who explicitly sees the future. Saro and Bragoon are not invincible. Without the prophecy, they could have been just killed by Raga Bol's gang, and reliance on them could have caused Redwallers to botch the defense. That's assuming that Martin can actually change and choose the future. The more specific and precise prophecies in a particular world are, the more frightening implications regarding the existence of free will they carry. And Redwall has rather precise prophecies. Martin might act in a certain way because he already knows he'll act in a cerrain way, and some instances when he undertakes clearly fruitless actions (like trying to scare off Cluny or Razzid) might be seen as confirming that.
Bats have a Verbal Tic of repeating the last couple of words in each sentence, each sentence. Living underground in caves most of their lives, including from infancy, the reason becomes clear; They've heard others speak, and the echo, from the time they were learning to speak. The echo was just mimicked the same as, and became part of, normal speech.
Possibly unintentional Fridge Squick when the Abbeybeasts joke about eating bad Dibbuns:
"But if you got eated for bein’ naughty, why are you still ‘ere?"
Fottlink whispered knowingly. “Because I was very young.”
Brinky went into some more deep thought before speaking. “Very, very young an’ only a tiny likkle beast?”
This may also fit under Fridge Horror, but... where do they get the milk to make all that cheese that's constantly mentioned as being present at feasts and such?
There is a reference to plant-based milk at least once. I think it's called greensap milk or something such. Not very well versed on the art of cheesemaking but there are several kinds of plant-based milk you can buy and it may be possible to use it to make cheese, even if it is not like most cheeses we'd know. There's also no such plant as hotroot in real life; the best guess is it's a bookverse nickname for horseradish.
I highly doubt Brian Jacques was implying they raped her. I believe they simply beat her (not that beating her is much better, but still). Remember, Mariel had suffered through a lot of trauma after they attacked her father's ship. That, combined with the night spent adrift in a stormy ocean and her loss of memory, are probably what contributed to her reluctance to recall anything she had just been through.
I know it's unlikely it was meant to be read that way, especially because as pointed out above Saltar's line about "feeding the fishes" implies that what they were actually doing is throwing her friends overboard, and Gabool seems more creepily interested in the bell than in her. But for pubescent female readers of a slightly paranoid disposition it's very easy to read it that way. Clogg and his crew leering at Celandine was mildly unnerving as well, even though we do know nothing at all actually happened that time.
Want some more fuel for paranoia? Think about why Mariel was the only slave of Gabool who earned a personal monicker from him.
To soothe it a little, reflect that she probably would have gone into Gullwhacker mode and fought back much sooner if that happened.
In Mariel of Redwall again, Rawnblade annihilates every living creature on board of the Waveblade in a fit of Bloodwrath. This carnage is already horrific enough - before you consider the fact, that every other ship in Gabool's fleet we see in any detail was crewed not only by searats, but also their oarslaves, and while the Waveblade is not explicitly stated to be the same, she is also not explicilty stated to differ in this regard.
Though this very likely fell under "I didn't consider that" on the author's part. But the books clearly state regardless that Badgers under the bloodwrath will kill anything in it's path, even allies.
The Sable Quean, sees the reappearance of the Flitcheye. Rather than killing them, the protagonists decide to take all the Flitcheye, tie them up in a grove, and burn piles of their own sedative herbs all around said grove. Then, they cheerfully continue on with their adventure. The idea is supposed to be "teehee, now you'll all wake up with killer headaches, that'll show you"...the characters don't seem to realize that administering massive doses of a sedative and then walking away is a surefire way to kill someone.
They are outside in the open air at the time, they have a chance. Still not good for them.
"The overhanging willows acted like an enveloping canopy, catching the smoke and holding it as it grew more dense." It was a crude gas chamber. They have a chance, but there's no way they're all making it out of there alive.
The only witnesses to Brother Hal's death were Dingeye and Thura, who fled and died soon after, missing their chance to tell the truth to the Abbeydwellers. Samkim and Arula likely went their whole lives thinking the Adorkable stoats they'd been befriending had intentionally murdered an Abbey mouse.
Mokug's backstory is rather disturbing when translated into human terms, as it involves an evil rich man picking a small boy as his slave because said boy is cute and blond. Squick. Highly doubtful Sarengo actually wanted him as anything worse than decoration, but...
