While Twilight was obviously freaking out and undergoing a mental breakdown from the fact that not only was the filly who for the longest time had been nothing more than one of the most power-hungry fillies in all of Equestria, who bought to destroy all Magic from the realm and imprison Twilight and her friends in Tartarus. But that said filly just so happened to be The DAUGHTER of Princess Celestia. Twilight for her part was at a complete loss as to how she should feel about this, wether to admonish the filly for her attitude or to hug her for how adorable she was or to bow down before her out of respect for Cozys’ mom.
 
While Spike comforted and consoled his rightfully freaking out mother, Cozy was being cradled slightly in the hooves of Celestia, the older Alicorn cooing as she planted kisses on her daughters’ forehead and sung her to sleep. For the first time in so long, Celestia was finally a mommy again. Luna had questions of her own regarding her Niece, as well as Cadence for the cousin she was completely unaware of. How did she come into existence? Who was her father, and if he was alive how could they find him? But looking down at the now slumbering filly resting in Celestias’ forehooves, the pair agreed that these were questions that would be better left for tomorrow.
 

 
The following morning was a very interesting one for Cozy; having thought that the events of last night where she was returned home to Canterlot and welcomed back by Celestia as her daughter, might have been nothing more than a delusion or tormented dream caused by Auntie Luna. But no, when Cozy awoke, she found herself not in a jagged stone cage atop a carved peak in Tartarus, battered by ethreal winds and enchanted thunderstorms; but instead she was in a warm bedroom with a dimly-lit fire glowing in the corner that drove away the chill from outside. Looking around, she found herself covered by a familiar yellow sun-emblazoned robe that served as a blanket for her, and that her own pillow that she was resting on seemed to rise and fall gently each moment, as though it were breathing. Cozy looked up and saw that the “pillow” she was resting against was Celestias’ tummy. It wasn’t a dream after all, this was all real. The young filly contemplated on getting up to head for the bathroom, yet couldn’t find herself any way to break away from her mommys’ embrace without accidentally awakening her in the process. So for a time, the second-youngest royal sat there resting her head against Celestia, trying to give both of them enough time as possible for the Sun Princess to sleep beside her until Cozys’ bladder reached its limit, forcing the young filly to slowly crawl her way out from Celestias’ bed and make her way to the bathroom.

I mean… that’s a little better…

Aww~ I just hate to see a poor creature suffering.  
*tosses her out into a snowbank, still stuck in a stocking, and closes the door*

or SCP-4666

This is too cruel. Just call Krampus and have him warm up her rump the other way.

Correct treatment of your Crazy Glue: she should stay in suspiciously skintight socks.

I suppose she’ll have to be let out at some point, but only once the holiday is over.  
Until then, this seems as good a place to keep her as any.

The pic looks awesome

It’s surely is very hot up there, this is torture

Sure she’s evil, but those tears just tug at the heartstrings.

@Background Pony #2B2F  
At least you’re not trapped in a Christmas stocking.

I don’t know if even Krampus would go that far. 0_o
 
@DrCoolcabbage  
Better not. This fluffy adorable menace already caused enough trouble.
 
@Napsack  
Eyyyyy~ :D
 
 
@Ohvist  
Now why did Twilight ever think that she’d have a sane life being the student of a near-immortal princess?
 
 
@redweasel  
Take the little grinch, noone else wants her apparently.

8/10 would cuddle wuddle, snuggle wuggle, and help ruin hearths warming

Surprisingly torturous.

@Havock
 
That would do the trick. Or just summon the Krampus to deal with Cozy.

@Antonyourknee  
How about a brass bull?

The solution is simple,pick her up,put her in a box..and throw that box in the fire.

I love coal!

Celestia wished to spend Hearthswarming Eve with her family… she didn’t expect that she would have to explain to her Sister why Cozy Glow was somehow stuffed into Celestias’ stocking, nor did she think that she would have to confess the truth that Cozy Glow was actually Celestias’ daughter. Though upon finding out about her niece, Luna proudly-accepted the little filly as part of the family and had her cleared of all charges regarding the previous year spent in Tartarus.  
Twilight rightfully freaked out about this.
 
Twilight: “Are you crazy! She tried to erase all magic in Equestria!”  
Celestia: “Twilight, the mark of our family is that at least once in our lives: we end up making one large cataclysmic mistake.”  
Luna: “Have you forgotten that I tried bringing about Eternal Night twice?”  
Cadence: “Or how Flurry ended up destroying the Crystal Heart?”  
Cozy Glow: “I wonder what your cataclysmic mistake will end up being Auntie Twilight?”  
Twilight: “…I think I already found out what my mistake was.”  
Celestia: “What was it?”  
Twilight: “Hoping for a sane life.”

They said they’d hang her, but she never saw this coming.

“I hate you with every fiber of my being… please let me out of here.”

Coal is only the beginning of the punishments given to the naughty.

Dang it, another Gremlins remake!?

Guess I was on the naughty list.

Now let’s not get carried away here. It’s one thing to be a murderous child, but being a child murderer is a whole other can of worms!

Conveniently, there’s a fire pit right there
