The #magic kit Jessie found in attic produced real magic! Of course her friends didn't believe her so... With Kev folded into origami swan, Hector pulled through wringer in flattened confusion, Ben and Quinn poof'd into dove and bunny, they must believe her now! Now how to undo? #Octransfur

Will be scampering around BLFC next week. Playing it low key and chill, but if wanna say hi, let me know. I'm a shy beast. (But still liable to pounce and/or bite.)

Maybe some dullahan (headless horseman) type creature? Type of mount and type of head unconventional? Who knoooows. In any case, best of luck exploring spoooooky things.

Trapped in cursed closet. Whenever opened, turned into whatever object one of the building's anthro residents is looking for. A rhino needs a mop. A boar needs a step ladder. A donkey needs a plunger. Being caught up in being useful and functional, eventually eager for closet to open...

"You're the one who didn't wanna be left #behind on this anthro-universe trip!" "Didn't know that meant I'd be covering your #behind for a week!" The newly minted rhino fellow adjusted his complaining boxer shorts. "Maybe will teach you to purchase tickets in advance next time." #Octransfur

Due to coding mishap, in near #future everything digitized, reducing everyone to little digital creatures content to scamper around a digital landscape. However, some critters contained flickering 0s and 1s buffering on "Error: something isn't right". Will patched out in next update. #Octransfur

Dr. Dillard tested the teleporter, unaware of his son's napping pet ferret in pod with him. The good news: the tech melded human/ferret DNA #together seamlessly (aka: anthro ferret) The bad news: Maybe *too* seamlessly, as they're so blended, might be tricky to unmix. *dook* #Octransfur

He insisted that the weed strain was super effective at getting him baked. You politely declined. Later, the smell of freshly baked bread filled the apartment. Is your friend #baking when stoned? Where is he? Why did he leave a loaf of sourdough on the couch? May as well try a slice... #Octransfur

Every TF app user guide warns against making an #Exchange with your pet. A day off work sounds great, but your pampered pup might not be so eager to give up their new thumbs. You might be staying like that for a while boy. In other words, everything was going according to plan.

(Just the secondary part of the dimensional exchange rate…)

Jasper Underbelly @jasperunderbelly.bsky.social · 02/10/2026
The #exchange rate was fantastic. One could get by on $5 (USD) for a week vacation. However there’s preliminary confusion when the ‘money’ given in exchange is a bag of sunflower seeds. Once step through dimensional portal and become a squirrel however… #octransfur

Luke's never been above tempting fate, even when his local Halloween shop seems eager to get rid of a black cat costume. Will the suit be a good fit, or is his luck about to run out? Faux Pass is back! Kicking spooky season off with a classic black cat TF. Enjoy! www.furaffinity.net/view/66544171/

At county #fair, you visit the "Guess Your Weight" booth. You chuckle at guess of "about five pounds". When you step onto the scale, your chuckle turns into clucking, your feathers ruffling as you shrink, recalling classic question "What's a henweigh?" (Turns out about *six* pounds.) #octransfur

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.
