20 euro - Rumpelstiltskin

The name Rumpelstilzchen in German means literally "little rattle stilt", a stilt being a post or pole that provides support for a structure. A rumpelstilt or rumpelstilz was consequently the name of a type of goblin, also called a pophart or poppart, that makes noises by rattling posts and rapping on planks. The meaning is similar to rumpelgeist ("rattle ghost") or poltergeist, a mischievous spirit that clatters and moves household objects. (Other related concepts are mummarts or boggarts and hobs, which are mischievous household spirits that disguise themselves.) The ending -chen is a German diminutive cognate to English -kin.
