In the latest episode of the Jack Hansard series, Ang and Jack run into a river-dwelling creature going by the name of Shellycoat. The reason such sprites are given this name should be immediately clear: they wear a rattling coat of shells over their body.
Now, I admit I had some trouble tracking down solid information on Shelly. My first search turned up several sites which all carried the same basic description mimicked by Wikipedia. I don’t wish to become part of the same annoying cycle, but the basic impression is simply: the Shellycoat is Scottish; lives in lakes, rivers and streams; and, like almost every other folkloric creature, has a mischievous nature.
The one solid lead I had was the knowledge that Shelly is mentioned in Jacob Grimm’s (yep, of the famous Brothers Grimm) Deutsche Mythologie. After a rather frustrating time trying to pinpoint the correct volume and page number (vol 2, p.512 in this translation), it turned out to say very little. According to Grimm the Shellycoat is a type of goblin, and he confirms that it is a Scottish creature. He then likens it to a dwarfish thing who wears a bell-coat (which elsewhere I’ve seen called a ‘Schellenrock’ or ‘bell-coat’). The bells worn on the hats and coats of fools are apparently a reference to this ‘shrewd and merry’ goblin.
A more colourful view of the Shellycoat is provided by Walter Scott in his Minstrelsy of the Scottish border (3rd ed), v1, which gives us an idea of the pranks Shelly like to play. Supposedly, he once led two travellers astray by calling out “Lost! Lost!” from the River Ettrick. The travellers followed this sound all night, assuming it to be a drowning person. They followed it all the way to the river’s source, only for the voice to head back down the river, back the way they had come. When they gave up their rescue effort, the Shellycoat revealed himself with laughter and applause, thoroughly amused with his own deception.
So Shelly may be a joker, but he seems to be fairly harmless, unlike a whole host of other water-dwellers whose sole intention was to lure travellers into the waves to drown.
It’s a bit funny that the most distinctive feature of the Shellycoat – y’know, his shelly coat – doesn’t seem to have much of a story to it. Does Shelly collect the shells himself? Does he wear them because they’re pretty or because they rattle in a musical way – like the bells the Schellenrock loves? Is it an actual garment like a coat, or more like a blanket-covering? I’m inclined to imagine the latter: picture this mass of shells creeping along the banks of a river, clinking and clacking as it moves. But it could be a more humanoid goblin like Grimm suggests; it might even help you around the home if you’re polite – so long as you don’t mind occasionally being tricked into a long walk down the river for no reason whatsoever.
