By many, goblins are considered less a race of small humanoid creatures and more a universal constant or a force of nature. Noisy, smelly, and worryingly numerous, they are a constant nuisance to any and all around them (though never catastrophically so). With nests across the multiverse, they have been likened to the common cold - in that what they lack in raw destructive power they easily make up for in hardiness and resilience to extermination (much to the chagrin of the more "cultured" civilisations who they revel in bothering).
I think my favourite goblins are Magic: the Gathering goblins, mainly due to the extent of their ineptitude (there's a running gag where goblin cards will do... like the opposite thing they ought to do - see Goblin Diplomats) and also their propensity for infighting and (*cough*) self-sacrifice. Plus, they're one of those creature types where you can easily flood the board with them, and my inner timmy lights up at the thought of swinging for lethal with 10,000+ goblins as facilitated by someone like Krenko.
Anyway! These goblins are inspired by Blanca's old 3d designs for goblins, which are slightly puggy, but also by the miniblin enemies from Wind Waker. I guess with the knobbly bits on their heads you might mistake them for some lesser devil or other, but from a folkloric perspective I think goblins/imps/bugbears/devils are all cut from kind of the same cloth, so I don't really mind.
