The Gilgoblins are a species of aquatic goblin, of which art was shown at BlizzCon 2009. The gilgoblin race is to be introduced with World of Warcraft: Cataclysm.

It is currently unknown whether they are a naturally recurring subrace or a freak mutation resulting from the goblins' Alchemy and Engineering experiments.Gilgoblins have many similarities to goblins but also many differences. Their skin is blue with tiny dots. Like goblins they have a prominent pointy nose, however the Gilgoblins nose seems to have no nostrils.  Their necks have what look to be gills which explains the absence of nostrils.
