These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Fiver again, especially in the film and TV series. Then again, it's hard to imagine how an adorable little rabbit who is totally lost without his big brother and who suffers from violent hallucinations wouldn't be a Woobie. He used to get kicked around a lot apparently and the rabbits who follow him need quite some time until they believe he DOES see things. And after the fight against the Efrafrans very detatched from their world, probably an after effect of the powers and spirits he channelled. Just the type of wild rabbit you would pick up, cuddle and take home if you'd find him half tharn in a meadow.
In the novel, Pipkin, as well. Even smaller and weaker than Fiver.
In the TV series, Campion also fits the bill. Sometimes.
Iron Woobie: Captain Holly in the film and especially the book. Survives his warren's destruction, gathers together a small group of survivors, only to have all but one of them die anyway, gets his ear ripped to shreds, and almost goes mad before he finally reaches Watership Down. And then he gets sent to Efrafa and just barely manages to lead his group out, though most of them are badly off. But he pulls through each trauma, shares the story for catharsis, and after he recovers he goes right back to work.
Mary Suetopia: What Watership Down seems to have become in Tales. The warren is a pioneer in democratic government, the protagonists are always ready to help any animal who comes to them with a problem, and they're always right.
Narm: Hyzenthlay telling a poem while Bigwig is spying in Efrafa is suitably dramatic and sad because it's a poem about how she can't produce a litter of kittens due to the warren being overcrowded. She finishes, and there's a moment of silence...then a bunch of bird poop drops down in front of them.
Nightmare Fuel: The White Blindess (Myxomatosis.) Keep in mind that it was deliberately introduced by humans to control the rabbit population.
One-Scene Wonder: The Black Rabbit of Inle only appears in one of Dandelion's stories, but it's one you'll never forget.
Paranoia Fuel: The book does an excellent job of making you know what it feels like to be an object of prey.
"Fiver Beyond" (basis for the Bright Eyes sequence)
"For El-Ahrairah to cry" (destruction of the warren)
"We followed [[the river]] down into a big wood; and that night, while we were still in the wood, Toadflax died. He was clear-headed for a short time before and I remember something he said. Bluebell had been saying that he knew the humans hated us for raiding their crops and gardens and Toadflax answered, "That wasn't why they destroyed the warren. It was just because we were in their way. They killed us to suit themselves."
"El-Ahrairah and the Black Rabbit of Inle"
Let's face it, the whole thing.
The poem of Hyzenthlay the Efrafan doe, quoted here
The beetles died in the frost and my heart is dark;
And I shall never choose a mate again.
The frost is falling, the frost falls into my body,
My nostrils, my ears are torpid under the frost.
The swift will come in the spring, crying “News! News!
Does, flow with milk and dig holes for your litters!”
Woolseyism: The translations from Lapine are sometimes presented this way. For example: Bigwig's name in Lapine is Thlayli. The literal meaning is "Fur-head", but "Bigwig" is an even more apt way of putting it, since he's also a senior officer of the warren.
Big Lipped Alligator Moment: The absolutely random part of the trip to Efrafa where Bigwig abruptly runs off from the group, we see a few pigeons getting scattered and he then rejoins them. He gives them a big story about his reasons for doing so and takes longer to explain the events than the scenario did to actually play out. It contributes nothing to the overall plot of the film and serves literally no purpose.
Bigwig was leading a fox away from the main group and unintentionally led it onto an Efrafan patrol and the fox killed one of them. It's explained better in the novel, but with this casualty plus the patrol run down by the train in their attempt to recapture Holly, Efrafa is running low on top quality Owsla. Hence it's easier for Bigwig as a newcomer to talk his way into a position.
Harsher in Hindsight: Keharr's final lines where he excitedly says he's going home to the Big Water. Zero Mostel suffered a fatal heart attack before the film was released.
Harsher in Hindsight: The cover of "Bright Eyes" that was recorded for this series was performed by Stephen Gately of the Irish Boy BandBoyzone. Most fan complaints over this were promptly silenced following Gately's death in 2009, and if anything, makes the song even more of a Tear Jerker.
The Scrappy: A lot of fans hate Primrose for being manipulative, self-centered, and good at nothing else. Particularly jarring if you realize that she's supposed to be Hyzenthlay, who in the book was intelligent, had a great deal of common sense and was a seer on top of it. Primose, in contrast, has few of those Hidden Depths, though she has her moments.
Strangled by the Red String: Campion and Blackberry. In the season 2 finale, they meet very briefly and barely have time to speak to each other before Campion's apparent death and their consequential separation. Of course, they pine for each other, and all the other characters, who are strangely aware the two's feelings for each other, try to comfort them for their loses.
Woobie: In addition to the examples above, there's Bark the rather needy badger - the Sole Survivor of her clan, living in a sett and terribly lonely.note Makes more sense when you realize Bark is a European Badger, which are highly social, versus an American Badger, which are the famously grumpy, solitary ones.
Fiver: Get it over with! Stop tormenting me! Just go ahead and kill me!
Which is sometimes Lampshaded by the narration, as when it's pointed out that rabbits feel no guilt or shame about using physical force to push weaker rabbits around.
And the two nightmare warrens are both, in different ways, attempts to beat a rabbit's harsh life as a prey animal. In one, the rabbits are protected from predators and have all the food they need—and are constantly culled by the silver wires. In the other, the rabbits successfully hide from predators and humans alike, at the cost of a horrible fascism. The lesson seems to be that if you're a rabbit, you need to just embrace the fact that everything wants you dead, and do your best with it.
Several. The Black Rabbit of Inlé, The Hole in the Sky, the Terrible Hay-Making...
The Hole in the Sky involves El-ahrairah hearing of the titular phenomenon and going in search of it. After losing a fight with a weasel and falling into an infection-driven fever, he unexpectedly finds it:
"Then he began to tremble with fear. In the blue curve of the sky he saw a great rent, a cleft which, he perceived, was an open, gaping wound. The two irregular edges were jagged as though it had been made with something blunt, something which had first cut and then ripped and torn. Here and there shreds of flesh, still attached to the edges, stuck out across the wound, obscuring whatever was behind. All that he could see in the suppurating depth of the wound was blood and pus, a glistening, viscous, uneven surface like a marsh. The edges were messy too, fringed all along with blood and yellow matter on which flies were walking. As he stared in horror, the dead body of a rabbit fell out of the wound, but disappeared as it fell."
What makes it even more disturbing is that Adams offers no explanation of what the Hole in the Sky is or what it means. It is, quite simply, a rabbit thing that humans would never understand.
Look at it this way: You've just read a description of a Lapine Eldritch Abomination; it is perceived only by those in the final stages of delirium and madness, it is beyond understanding except to the insane, and those that have seen it are marked forever.
