Woops, sorry… that was from the Gods of Pegana, published in 1905.
I thought it was neat that the pantheon we’re building here goes so far back in time.
— Nintendo imps - freaky little bastards who live in Nintendos. There are many other imp varieties but this is the one I am the most familiar with. They toture game players by giving the COM opponents unfair boosts of abilities at random sites. They feed of frustration.
— Remote Control Gnomes - They hide when your around but when you leave to go to the bathroom they change the channel and move the RC so you can’t find it and have to suffer watching Lifetime cause you wont walk across the room to change the channel. There are many variaties of these namely Key Gnomes and the worst offenders of all Glasses Gnomes.
— VCR Fairies - They live in the electronics and make sure that any automatic recording starts either 2 minutes late or 2 minutes early.
— Toilet Trolls (MarxBoy) - I have met them and one of their meanest tricks is to emit high powered jets of air so as to split urine streams into two and cause messes.
— Bed Demons - These evil creatures are known to desire to possess that bodies of the victims who sleep in their beds and cause certain late night emmisions. They come in three colors. Yellow demons attack young children, although drunks may also be their victims. White demons attack adolescent males. Blue demons attack older males. You never see them but you know when they’ve attacked.
Bless you, MrVisible! So few people know of Lord Dunsany today. His writings are so beautiful. I wish more of them were in print.
It doesn’t rhyme and it’s no alliteration, but there’s just something scary about Duct Monkeys.
Are you sure you’re not referring to Game Sprites, br’er rat? 
Here are few fresh ones:
Fir(eplace) Darrig :eek:
Card kobolds, a subspecies of kitchen kobolds that feeds on single playing cards from every deck in the kitchen junk drawer. (I hope they never develop a taste for MtG cards and go foraging.)
Totoro mentioned change sprites, but I suspect that he’s been unfairly blaming the benevolent sprites (who find loose change and add it to your piles when you’re not looking) for the pranks of the changelings, who hide all of your high-denomination change behind the dryer/desk/wainscoting and leave only pennies behind.
I had to add my own personal household demons, such as the:
Car Key Kenders - They steal your keys and put them in the oddest of places immaginable, like the freezer.
Door Demons - When you arent watching, they rush to open the doors and let all the bugs into the house. Closely related to Window Masters.
Sterio Wraiths - They turn your sterio to the polka radio station and set it to the highest level while you arent looking. When you turn it on : Suprise!
Uh…yeah.
Pen dragons. They’re the ones that hoard all your writing implements.
Pant Lions. Their job is making sure there’s fur on every black pair of pants you own, even if you’ve never seen an animal.
And this may not be a household thing, but they’re definitely in my own personal mythology…
Vampire cars.
They’re the ones that don’t show up in the rear view mirror, so you don’t notice them until you’re actually changing lanes.
How about…
Sunglasses Minotaurs
They hide your glasses in the center of their massive labrynth, never to be found again.
House hippos!
Please tell me someone else has seen that commercial…
Nope, but I remember the Far Side with the elephant hiding behind the furniture.
New ones:
Fizz faeries, who are responsible for loosening the caps on carbonated beverages so they go flat.
Fantoms–the source of those really odd noises the ceiling fans make from time to time. They also rattle the switch chains.
(Did everyone actually get “Sidhets”? I thought that even in this clever crowd, there would be at least one person who didn’t know how to pronounce it.)
Fashion Imps. They’re the ones that make sure that whatever you choose to wear to work in the morning looks just plain wrong.
Goblets - small imps that run around and break glasses in your cupboards.
And on Doplehangers:
For years and years my dad never had enough hangers. never. He’d double hang pants and shirts. So he’d buy hangers a lot. Piles of them. Still never had enough hangers. Years went by. Ten years later he talked to my mom about hangers. She had a similar problem, for years and years she’d had too many hangers. They would clutter up her closet until she felt she was drowning in them. No matter how many she would throw away…
Milk Cap-prechauns
Like their cousins, leprechauns, Milk Cap-prechauns are mischievous creatures who delight in stealing dropped milk caps before they even hit the ground, leaving their hapless victims to wonder where the milk cap went (and eventually sealing up the milk jug with a rubber band and a bit of plastic wrap). It is said that a captured Milk Cap-prechaun an be forced to reveal his magical pot of sour cream, but it’s hardly worth the effort.
Bread Twistie Faeries.
A friendly breed of artistic faerie who delights in decorating infrequently used kitchen drawers with those little multicolored plastic thingies you see pinching together bread bags. They are sometimes known to augment their artwork with breadcrumbs, dried peas, and loose elbow macaroni.
Soy Sauce Spectors
These are the tormented souls of Chinese take-out cooks who have disgraced their ancestors by short-changing the shrimp in their customers Spicy Prawn Balls, and thus are damned to wander the afterlife filling the kitchens of bachelors homes with Soy Sauce and Spicy Mustard packets.
I just taught my niece about one of these - The Giant Sabre-Tooth Dust Kitty. It hides under the bed and bites the feet off nose-pickers.
I was also wondering about the Post Toastie Ghosties. You know, when you hear the cereal in the box when you shake it, but you turn the box over and nothing pours into the bowl?
Brrrrrrr. Gives me the willies. And now I have to worry about Dopplehangers, too…
The idea of household mythology goes back much further than Lord Dunsany. Virually all cultures with an animistic religion had household gods, guardian spirits, and “small gods.” In Roman times, the penates were gods of household storage, associated with the goddess of the hearth, Vesta, and the lares, household guardian spirits.
If I recall correctly, the Roman penates and lares were considered “small gods,” not important enough to be ranked with Jupiter, Neptune, and the rest. This may actually be where Dunsany got the idea for his household gods, since the Romans were known to have some spirit or agency responsible for every phenomenon.
The general term for this religious belief is animism.
Of course, if I had edited my post, I would have realized that I’d already mentioned the term animism, and defined it in context.
Apologies.
Door Lock Ness Monstaer
Hamper Hobbits
The dreaded Shower Yeti
Wargdrobes.
Orcscrews.
Toilet paper gnomes - steal the roll that you’re sure you put there, just a second ago. Bastards.
Keyringwraiths - One ring to rule them all, one ring to bind them, one wraith to hide them all and ensure you never find them.
Good ones, DynoSaur.
Hopsgoblins–indispensable assistants to homebrewers everywhere.
Burgling behinders–these only come out to play when we’re irrationally certain that someone has broken in, only we can’t find them. When not hiding behind your back, they commonly lurk in showers with opaque curtains.
Toggle boggles–prankish creatures who turn off lights we’ve left on and turn on lights we’ve left off.
And how can we have missed the brownie brownies–mishievous little imps who steal our fresh-baked sweets? Perhaps the impending visit of my niece and nephew reminded me…
