- "You never seen a gilblin before? They're crazy! Crazier than me! I just blow stuff up for a living, these guys are WHACKED! Dunno where they came from, but they're like awful fish goblins! Gills and everything!"

The gilgoblins, sometimes called gilblins, gill goblins, or water-goblins, are a species of aquatic goblin created by Hobart Grapplehammer. They were first introduced into the game with the World of Warcraft: Cataclysm expansion and can mainly be found in the depths of Vashj'ir, though one group has invaded the coast of the Swamp of Sorrows as well.
Gilgoblins have many similarities to goblins but also many differences. Their skin is blue or red with tiny dots. Like goblins, they have a prominent pointy nose, but the gilgoblins' noses seem to lack nostrils. Their necks have what look to be gills, which would explain the absence of nostrils. Gilgoblins have fins on the ends of their arms, with webbed hands and feet almost certainly for swimming. Their hair resembles seaweed and their ears are practically fins.
The adaptations that allow gilgoblins to survive the aquatic life has apparently drained some of their higher brain functions and their actions are guided almost entirely by greed. They are most often seen stealing things.
and both note that the gilgoblins are quite primitive, and that they seem intensely curious about their advanced equipment, sometimes suicidally so. The gilgoblins of Vashj'ir hold the naga sea witch Lady La-La in high regard.
Gilgoblins live in big clams, which they decorate with their new-found treasure, including cannons, cannonballs and other things.

It's likely that the creation of the gilgoblins was an accident as Hobart Grapplehammer (the creator) has a negligence case because of it. Although at times he's proud to include them in a list of accomplishments.
