I've a growing suspicion.
It has to do with raccoons.
And our favorite green men, goblins.
Here me out here: Raccoons may be as close as we in the mundane world get to interacting with goblins.
Think of the attributes of a goblin: small, mischievous, stupid but devilishly clever, creepy hands, they are most active at night, their teeth are small but sharp, and while they are a nuisance alone they are a terror in large groups.
Now think of raccoons, everything in the above list can be applied to them.
So for your delight, photographic proof that raccoons and goblins might as well be the same:

|Might as well be a raccoon|

|They both seem fascinated with shiny things|
And to finish it off, a gif of a raccoon climbing a crane (when I saw this i was genuinely surprised, it moves like a humanoid!):
