from what I recall, the suits all had those prototype talismans, but they were just there as a backup if the primary system crashed. for most foals, the pink cloud didn’t damage the primary system of their suit at all, but it was about as effective as tissue paper. some ghoulified, the rest melted in their suits. for puppysmiles, her primary system randomly glitched out in a complete coincidence, the moment she was about to melt, letting all that untested necromancy come online, which actually somehow worked to keep her alive where the primary system would have failed.
 
matter of fact there’s nothing saying that the glitch didn’t happen in any other suits. puppysmiles did sit dormant for 150 years before the roof fell on her and woke her up. which is a really freaking durable roof, if you ask me. but there could be other “empty” suits in canterlot, with the secondary talisman active, waiting for something to awaken them…
 
though considering what her suit did the one time it was torn to shreds, I think it’s safe to say both puppy and her suit had become something… More than what the suits normally were.

As far as I know, her suit was some kind of prototype with a necromantic talisman, while the others from the Lost Herd were just hazmat suits. Her soul was trapped inside that “body” along with the entity known as Nightmare Noob (Creepy voice).

that….would explain the rage moments…

@Prysmfox  
If anything, she’s more like a windigo made of pink-cloud trapped inside an exoskeleton.

reanimated goo monster inside a well maintained suit (beter so then any of the others) ghost eh same diffrence (…i wonder why all the other members of the ghost herd’s suits failed when hers didnt…they have been runing every bit as long and exposed to the elements, hell if anything pupppy smiles should be in worse condition as it was directly exposed to the pink cloud (internaly and externaly) for well over a century….did the story ever explain that…i cant remember its been awhile…

Now she looks like the Ghost of the 52 that she is.
