Yes, you're right, Mrrzy. I think (maybe) Rumpelstilskin is referred to as a "dwarf" in some translations.

But -- that is a name for a specific type of supernatural being related to fairies and elves. The use of "Dwarf" to refer to humans with a genetic trait of disproportionally short limbs is borrowed from the folklore belief, if I am not mistaken.

And, Thanks, Mrrzy!
