Spooky season is almost here, and you know what that means: Costume TFs! Last year I created the Faux Pass story series to pay homage to all the classic costume shop TF tropes. I'm looking forward to revisiting the series next month. Time for a recap thread! www.furaffinity.net/gallery/here...

Took some effort to convince trickster demigod that opinions while turned into object aren't reliable: "But you loved cutting grass so much!" "Of course I did! I was a lawnmower!" "...I'm still confused what the issue is. Know what would help you relax..." "Don't you d-" *lawnmower'd*

Feels like most animal body swap caption photos I see when searching are "look at this human doing animal things in humiliating (usually sexual) fashion!" when what I really want is post-swap photos that look like this:
Snake attempting to take a shower. 
Squirrel attempting to have a smoke and beer. Ferret attempting to record a podcast. Raccoon attempting to read a book.

Fun when a character is "we'll fix this TF in a few days..." followed by [THREE MONTHS LATER] A TF situation can be elevated by a well placed time skip~

Getting all my ducks in a row for spooky season. 🎃 Bit of a lighter posting schedule this year. Y'all remember Faux Pass, right? Cozy costume shop TF setting? www.furaffinity.net/view/62472333/ Really looking forward to finally posting a Werewolf Wednesday two-parter too.
A posting schedule of 7 different stories. Faux Pass on Sundays with Black Cat, Robot, Day Off, Jack o' Lantern, and Satyr. A werewolf two-parter story is on two different Werewolf Wednesdays.

Thought would be clever way to transport/hide a dozen anthro fellows by converting them into a magazine. Guess should have predicted the magazine would end up being more erotica flavored, with photos of those involved in provocative poses and states of undress. Hmm. That rabbit pinup is nice...

Someone insists they like the "inconvenience" of a TF remote because it allows to sample what's available that wouldn't consider otherwise. Though it seems to parallel to TV channel surfing in weird ways. Like the subject's original form is only available on Tuesdays at 2:30 PM on Channel 31...

Trickster who's changes undo by next day so they figure why not use reality altering powers to shift anyone nearby into clothing or food or whatever is needed. Everything is totally normal my next morning so why limit one's self? (The memories of the experience remain for those changed though...)

After thinking it for a long time, you decide to go help your community by becoming a firefighter. You head on to the station, but after looking at your resume, seems like you don't fit the bill. But don't worry, there's still a spot as a fire hydrant next to the dog park if you want it?

If you have *one* TF option at hand, recommend [dog TF/full-dog-brain]. Will defuse most (if not all) heated situations. Mood will immediately improve for everyone involved. On other side subject(s) will just remember feeling Really Good. (Don't tell them why their mouth tastes funky.)

Pet that can swap bodies with owner whenever they want. Yeah, the dog will inevitably swap back into his body. Because he loves being a dog best. But to avoid annoying stuff like the vet or a bath or anything, a quick swap helps~ Also best easy way to get human snacks (and other human stuff)~

Cursed Fire Hydrant: Whenever a dog marks its territory on this hydrant, triggers body swap between dog and its owner (or nearest available human). (Unclear how curse is undone, as human-in-dog's-body marking hydrant does not produce the swapping effect.)

Be careful letting your friend turn himself into a dog first...and letting him still hold the TF Plot Device. But because in going dog brain might turn the rest of your friends and you into dog things~ I'm sure you'll be a good tennis ball for your dog friend.

Whoa! Check out this shiny egg thing! Just gonna grab this and...uh...w-what's going on...this feels...weird...and iconic??? #TF 🦝💨🦎 (Saw GOAT and was like...what if Modo? Modo-ification sequence by the fantastic @commissark.bsky.social~)
Sketch/art TF sequence. 
Geo (raccoon in vest and newsboy cap) sees a faberge egg and gets all grabby paws. 
The raccoon jumps upon the egg and his tail bursts out into a big thick reptile tail. 
As he looks back at new tail, his left paw POOFS into a big reptile paw gripping the egg. Suddenly, his right leg POOFS into a big reptile leg, making Geo look rather disoriented, dropping the egg. 
A big reptile paw reaches down, gripping Geo's raccoon hed, then yanking him upwards, obscuring his form into......into Modo Olachenko, komodo dragon lizard creature thing from the movie GOAT. There's puffs of pink smoke about and the lizard thing is wearing Geo's blue vest and red newsboy cap (with horn/spike thing poking out). He's holding the faberge egg, admiring it, he's balanced on his tail and drooling and just looking like a scrungly reptile dude rather than a small scrungly raccoon creature.
