These hyper-cranky beings are always serious, seeing life through the eyes of someone who is perpetually constipated. They are forever miserable, and whine incessantly.

The Goola-Goola is a tinkerer extraordinare, believing that anything can be fixed, even if it is working fine. If there are a few extra screws when repairs are done, so what. What's the problem As long as it works. Space dwarves have been known to get so excited when they are working on unfamiliar projects, that they occasionally pass out from hyper ventilation. When covered with grease and surrounded by a million parts, strewn all over the place, the dwarves' nasty temperament changes and they become almost happy.

The dwarves travel around the galaxy, looking for things to fix. The quest for some rare tool that somehow might enable them to repair things faster. They always have widgets and doohickeys galore, carrying around tools that most people have never seen before.

Space Dwarves will try to fix anything. That's the problem. Goola-Goolas don't believe that they are ever doing it wrong. Letting one tinker with any type of equipment can be a bad mistake. If the equipment is important to the survival of the party, such tinkering can be fatal. If something is broken, the space dwarf will insist that he alone fixes it and there is reasonable probability that he will.

Whatever you do, keep the Space dwarf away from anyone who has cybernetic implants. The Goola-Goola become crazed at the mention of the word bionic! Their intense curiosity drives them to discover the exact wonders of cybernetics. Thus, one of the party may well wake up with the space dwarf disassembling them.
