“The Crumple-Horned Snorkack ...is a shy and highly magical creature..."
-- Xenophilius Lovegood (DH20)
Elusive, non-flying creature that lives in Sweden, which seems to be very popular among readers of The Quibbler.
Saying that an animal is crumple-horned means that its horns curl in spirals.
snork Eng. a young pig (NSOED).
The Crumple-Horned Snorkack is possibly a reference to the poem "The Hunting of the Snark" by Lewis Carrol , which tells the story of a creature no one can find.
. . . But the Snark is at hand, let me tell you again!
'Tis your glorious duty to seek it!
"To seek it with thimbles, to seek it with care;
To pursue it with forks and hope;
To threaten its life with a railway-share;
To charm it with smiles and soap!
"For the Snark's a peculiar creature, that won't
Be caught in a commonplace way.
Do all that you know, and try all that you don't:
Not a chance must be wasted to-day!
