- "The world’s largest kelpie is found in Loch Ness, Scotland. Its favourite form is that of a sea serpent. International Confederation of Wizard observers realised that they were not dealing with a true serpent when they saw it turn into an otter on the approach of a team of Muggle investigators and then transform back into a serpent when the coast was clear."

Its favourite shape is that of a Sea serpent. Wizard observers from the International Confederation of Wizards discovered it was a Kelpie when they observed it changing into an otter on the approach of a team of Muggle investigators, then back into a Sea Serpent. The Office of Misinformation has worked diligently, convincing the Muggles that all photographic evidence of "Nessie" is actually fake.
Behind the scenes
- The Loch Ness Monster is a creature believed by some to live in Loch Ness, Scotland. Though it is most commonly identified as a plesiosaur-like creature, sea serpent depictions are not uncommon either. The reference to the Office of Misinformation discounting photographic evidence may be in reference to the "sturgeon's photograph", which was once considered plausible evidence of the Loch Ness Monster's existence but is in more recent years believed to have been a hoax.
- It is possible that the kelpie seen in Wonderbook: Book of Spells is intended to be the Loch Ness Monster, as it is rather large, lives in a Scottish loch, and takes the form of what appears to be a sea serpent, rather than the horse form the species generally takes.
