Fuchsteufelwild

A Fuchsteufelwild (pl: -wilder, German: literally "fox devil ferocious", best translated as "mad as hell") is a goblin-like Wesen that first appeared in.

Biology
Their fingernails extend into long, sharp blade-bones when woged. Fuchsteufelwild's muscles secrete a highly concentrated acid, allowing their blade-bones to burn and slice through their victims like butter. They are typically ill-tempered and small in stature but incredibly agile. While woged, their hair turns darker.

Behavior
Their large egos fuel their capacity for horrible and cunning acts of violence. Fuchsteufelwilds love to play intricate games with their victims. It appears that all Fuchsteufelwilds have names that are anagrams of Rumpelstiltskin.

Excerpt from Grimm Diaries
''This ill-tempered creature is small in stature but capable of horrible and cunning sets of violence. He has an immense ego for such a nasty little beast.''

''One might be inclined to laugh at him but it is not advisable for he is equipped with fierce bone-like fingers and powerful legs. His leap is far and his stomp can cause the earth to shutter beneath him. Its muscles secrete a highly concentrated acid allowing them to burn and slice through victims.''

In the Wesen state, this beast's fingers become two digits and two extraordinary bone-like nails.

Trivia

 * In, the Fuchsteufelwild's name is "Trinket Lipslums" which, like all names of Fuchsteufelwilds, is an anagram for "Rumpelstiltskin"
