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.
Ensemble Dark Horse: Toad. He's by far the most popular character and tends to get top billing in just about every adaptation there is.
Ho Yay: Mole and Water Rat show shades of this. Living together is possibly the least intimate gesture that passes between them. Terry Pratchett commented that "the Mole and the Rat's domestic arrangements are probably acceptable, but only if they come out and talk frankly about them."
Nightmare Fuel: "Secret of Survival" may not be the scariest song ever, but it's still the darkest part of the Terry Jones version.
