Spacegoblin (Starfinder)

The infamous Space Goblin.

Here a short descritpion from The Starfinder Alien Archive :

'Goblin legend claims that long ago, a tribe of surprisingly clever goblins stowed away on a spacecraft.

Over time, the goblins learned to build weapons and armor from scavenged parts, though many of their efforts are prone to exploding at the slightest provocation. While space goblins have since managed to hijack other ships and spread to the stars.

Thanks to the goblins’ rapid reproduction rate, many generations have passed since those first goblins came. Fluctuating gravity, an entirely new diet, and the occasional radiation leak have made space goblins a distinct offshoot species from goblins. They are a bit more intelligent, instinctively able to take apart technology and rebuild it to suit their strange whims. They are quicker as well, scuttling rapidly into nearby ventilation ducts after swiping unattended datapads or laser pistols.'
