Goblins are very sneaky, mischievous creatures. Although, they are not completely evil, they show no fear in playing pranks on the humans they come in close contact to. They enjoy rearranging things to cause confusion, making loud noises, and disturbing others. Their small stature allows the, to do so without being seen.
A goblin’s smile curdles the blood, and the laugh sours the milk, and makes fruit fall from trees[1]. The tricks they play on people are sometimes enough to seriously harm them.

Origin: Goblins originated in areas of France and quickly spread all over Europe, but they stayed mostly in places such as Britain and Germany. They were nomadic creatures who got rides with Viking ships and temporarily lives in mossy cracks on rocks or in tree roots. Others say they lived in mines where they searched for riches, and trouble of all sorts.

Appearance: The goblin is a very small creature, only growing to be around 30 centimeters tall. They are covered in a thick coat of black/grey hair and are almost always wearing dark clothing[2]. Some are also found sporting armour and weapons.

Influences of the Modern Day: The goblin in more popularly known from the comic book series Spiderman where one of Spiderman’s biggest rivals is a character who calls himself the Green Goblin (also the alter ego of industrialist Norman Osborn[3].) His character also carries on to the Spiderman animated series and the 2002 Spider-Man movie.
Also, the phrase ‘Ghosts and Goblins’ is something commonly associated with Halloween.
