@Clever Clovers
It definitely works, like I love the idea of artificially-created things gaining a sense of self :D

@Badumsquish
(Badum, just a heads up: this may be the longest comment I’ve ever made on the site, but trust me, you’re gonna want to read the whole thing.)

A bit late to this, but I think that the Tantabus was around for a lot longer than that…in fact, I got a whole freaking theory/headcannon about it.

While Luna did say the Tantabus was her own creation made to punish herself for Nightmare Moon’s misdeeds, she never said she had created Tanti after Twilight beat her…or any specifics on when Tanti was created, for that matter!

With that in mind, my theory/headcannon on this is that Luna created her LONG before she had actually became Nightmare Moon in the first place, most likely back when she and Celestia were both fillies. The Tantabus was probably originally created as some kind of “imaginary friend”-type creature for Luna to have fun with when she was sleeping, and as her tastes matured, Tanti didn’t go away, instead she provided those newer tastes for her in the dream realm so Luna could still have fun with her. However, after returning from banishment from the moon and being turned back into Luna again, Tanti was forcefully repurposed by Luna to constantly punish her for what she did as Moon, and eventually, Tanti became corrupted by the nightmares Luna made her create, and decided to go into other ponies dreams to corrupt them. Then, after the Mane 6 helped Luna defeat the Tantabus, she absorbed her back into her own mind. Afterward, Luna not only had a peaceful sleep from that moment onwards, but Tanti was back to her old self again, ready to give Luna some great times in the dream realm again, just like before she was corrupted.

…I spent, like, half an hour on that. I had no idea I had sunked that much time into this comment until I looked at the clock.

@WitherGod
Not only you, i’d love to wear that too. Seems comfortable

Holy crap I’d LOVE to wear that

@Background Pony #EA0A
@Background Pony #EAFE
It’s definitely something I gotta put thought into XD

@Clever Clovers
Tantabus has spent her entire existence, what must be like three years, doing nothing other than a calculated effort to make Luna more emo. She’s pretty pent up XD

@Badumsquish
It does? Raridash almighty, that makes it about 10 times harder…

@Background Pony #EA0A
What about the tantabus makes applejack wear a frilly dress while she eats out applejack

@Badumsquish
How about the tantabus makes applejack futa and she only cums strawberry cum

@Background Pony #EA0A
@Clever Clovers
It has to be sexy and involve Tantabus directly though :D

@Background Pony #EA0A
Oh my goodness, that one is perfect.

In the case of the remaining 4 out of the Mane 6:

Twilight: The Tantabus makes Twilight relive all her past fights with Equestria’s villains, but instead of being against the bad guys, she’s actually on their side, actually helping the bad guys win against her will!

Fluttershy: The Tantabus makes Fluttershy Angel’s pet, and I think Tanti knows just as much as we do how much of a bunny bastard that rabbit can be to her…

Pinkie Pie: The Tantibus puts Pinkie in front of a big crowd, but makes it so all of her jokes aren’t funny, to the point where the entire crowd (which includes her own friends) start hurling tomatoes at her.

Rarity: The Tantibus makes all of Rarity’s dresses ugly, and makes her model all of them in front of all the other elite fashionistas in Canterlot (plus Sassy Saddles just to add more salt in the wound).

@Badumsquish
How about a pear eating applejack

@Background Pony #EA0A
I want to do nightmares for all of them, but I haven’t thought of one for her yet XD

@Badumsquish
Would applejack have the same nightmare from the tantabus?

@Background Pony #EA0A
Oh totally. Right now she has full control over Dashie’s body, but she’s largely just making her do girly things in public since that’s Dashie’s worst nightmare XD

Can the tantabus make rainbow dash futa?

tabatabus are useful D:

Wow huh huh huh this Tantabus thing is good hu huh now is Rainbow Dash for you know huh huh my wiener huh huh

@Nittany Discord  
Makes me wonder if Luna secretly has some kind of dress-up fetish if the Tantabus keeps pulling stunts like this XD

Rarity + Tantabus = New line of living nightmare fashion. It’ll be the hottest new trend since the Nightmare Dress Monsters.

@Dirty Bit  
@Wayneponeth  
It knows ponies fears, but it also has its own wants and needs XD
 
@Background Pony #EA0A  
She will never admit it, but she knows it XD

Rainbow has to admit she looks cute

@Badumsquish  
I’m sure even Tantabus finds Dashie cute. :3

Very adorasexy

@Badumsquish  
Point taken.

@Setsugekka  
It’s surprisingly good at clothes XD
 
@Train Track  
Also to a lot of other folks watching XD
 
@Clever Clovers  
It did it’s job though. I’d rather see a villain leave with missed potential than be ground into the ground :D
 
@Nittany Discord  
Dashie doesn’t :P
 
@Mellow Rhythm  
@Power-Up&Sky-Blue  
@Wayneponeth  
@Peternators  
@Train Track  
A lot of it is it’s moving her body against her will. Something the Tantabus seems to have an affinity for XD
 
@Background Pony #9CD6  
Who knows what else it has up its sleeves XD
 
@JP  
It’ll find a way to get into the waking world sooner or later :P
