She only surfaces every now and again. Her main food, sea-haggis, has one fin shorter than the other, forcing it to swim in ever-decreasing circles. Easy prey, even for a giant but clumsy sea-serpent.
Tourists, particularly Americans and Japanese, travel from all points of the compass to see her, calling from the shore in the hope that she'll appear conveniently for their smartphone selfies. She never will, though. Only one little boy, a local, knows her name is really 'Eva-Ann', and she comes to him, when he's alone, at dusk.
She might live in Loch Ness, but "Nessie" she ain't.
