Children, who for some reason, have parents that can't give them enough attention. If you are kind to them, they'll come to your home, eat all your food, fuck up your property, test your sanity then go home pouting when you finally insist. Their parents are none the wiser. These kids usually tell really bad lies.
"There are some people I'd like to have over, but their kids are gremlins. It's not worth the headache."

you can see gremlins if you are in a bathtub in the Mystical Thatched House of Pube, near the evil elf forest of Pubical features. Gremlins can sometimes be helpful, sometimes they can be spiteful if you have been smoking too much pot. if you are ever poked by a gremlin's magical nightstick, get yourself to a cupboard as fast as you can and listen to banana phone for ten hours.
