Looking for a tyipicall goblin who helps around a house but moves objects and loose them.                             

Goblins are Faeries, not mythical beast.

Goblins are not little green fellows with pointy ears...

They are not Servants either, they are Fairies that are highly dangerous.

Fan, the creature you are thinking of is a Brownie not a Goblin. No fey is a servant. They won't do your chores for you & they cannot be controlled. Until you understand the fey better, do not attempt to contact any of the fey races as the malicious fey will trick you & make their way into your home even though they aren't who you were trying to reach.

I find this thread pretty amusing, since the word "goblin" comes from the word "kobold", which was a mischievous and sometimes outright malicious spirit.
How someone could think of bossing around a spirit that gets its jollies by farking up your day, I haven't the faintest idea.

Oh Kreepy, we are actually agreeing again! You are very right about Kobolds. I think someone may be taking Harry Potter a little too seriously. There are no Doby the House Elf types that will do whatever you want. And if there were, Goblins would probably kick their ***, that's just the kind of creatures they are.
