Jacob Grimm stated in his Deutsche Mythologie that the Scottish goblin Shellycoat is one and the same as the German Schellenrock, that is bell-coat:
"A pück [home-sprite] served the monks of a Mecklenburg monastery for thirty years, in kitchen, stall and elsewhere; he was thoroughly good-natured, and only bargained for 'tunicam de diversis coloribus, et tintinnabulis plenam.' [a "parti-coloured coat with tinkling bells"] In Scotland there lived a goblin Shellycoat, and we saw (p. 465) that the dwarfs of the Mid. Ages also loved bells (schellen; and schellenkappe is Germ. for cap and bells) The bells on the dress of a fool still attest his affinity to the shrewd and merry goblin (fol, follet); see Suppl.'"
