They were very clever with their hands. They liked to make engines of destruction and things that exploded.
According to J.R.R. Tolkien they glow in the presence of ogres and orcs and goblins.
Tolkien may have left the appearance of goblins vague to allow readers to use their imagination and create their own scary images. By providing fewer details, he could also focus more on the actions and characteristics of the goblins, contributing to their menacing presence in the story. Additionally, leaving out specific physical descriptions may add to the mysterious and mythical quality of these creatures.

Tolkien describes the wargs in "The Hobbit" as large, fierce, evil wolves that are in league with goblins and are under the control of the goblin leader, the Great Goblin. They are depicted as being cunning, cruel, and capable of communication with one another.
The evil wolf-like creatures that support goblins are often referred to as "Worgs." In various fantasy settings, including Dungeons & Dragons and Tolkien's works, Worgs are depicted as large, intelligent wolves that serve as mounts and allies to goblins and other dark creatures. They are known for their cunning and ferocity in battle.
That is for J.R.R Tolkien and only J.R.R Tolkien to answer. It is not for us to judge, we just enjoy.
J.R.R. Tolkien wrote a series of novels about Orcs, Hobbits, Goblins and Elves. The novels in which these kinds of characters are mentioned include:The HobbitThe Lord of the RingsThe Book of Lost Tales
When The Hobbit was written, I don't think that Tolkien had imagined that the Orcs/Goblins were derived from the Elves. In many ways the Goblins of the Misty Mountains were somewhat to the Silvan Elves of the Woodland Realm: - They both lived underground - They both were suspicious of outsiders (especially dwarves) How they differed: - Goblins preferred the dark places and shunned daylight, Elves lived underground to avoid detection - The Elves were beautiful, the goblins ugly - The Elves only greed was for wine and song, while the Goblins were just plain greedy This is just on the surface too. Later we are told that the Goblins/Orcs are actually Elves that were twisted and corrupted by Morgoth, Sauron's master.
They use their imaginations, and the descriptions that Tolkien gave us in Lord of the Rings.
At the end of chapter 17 of The Hobbit by J.R.R. Tolkien, when it seems as if the goblins will destroy the elves, dwarves, and men, it is the Eagles who appear in the nick of time to aid in the battle, led by the great Eagle of the Misty Mountains.
