The suit begins to deflate and flop down on the couch. The head turned around the room. Almost as if it was looking for something.

“Hmmm…. Does that mean you give up?” He asks, assuming he is wrong
In response the suit began to undo its zipper. The suits inner walls seemed to be cushioned. The suit then began to claw at the furniture. It wasn't leaving any marks. It was clear that it couldn't really cut anything with its talons.

“So… a magical alive suit wants me to wear it… Because that sounds completely safe for me, not like the suit can overpower me while I’m inside and do who knows what” He really doesn’t trust it.
Once it was filled the now animate suit sat and patted the couch it was sitting on. A sipper could be clearly seen on the front of the suit.

“You want me to sit right next to you… Give me one good reason I should comply and not run away”
As if in response the suit unfolded and stretched itself out flat on the couch. Its limbs seemed to be slowly inflating to Griffon proportions.

“…” He looks at it shocked, but then shakes his head “Knew it… I fucking knew it… This thing is posessed, probably souls of long dead griffons”
Treasure chest opened! You acquired... a rubber blowfish colored like Princess Celestia? What.

He looks at the thing dumbfounded “Alright, now I KNOW somebody set this chest up, this is just too bizarre”
Could it be this suit was magical somehow? If it was it was apparently trying pretty hard to get his attention.

He gets an idea and tries it out, hoping nobody can see him “Alright… suit. You have my attention… What do you want”
After setting the chest ablaze and returning inside Pewny would find the suit and stalkings laying neatly on his couch. But how could that be even remotely possible? They had been burned along with the chest. Could somepony be messing with him? If so, how could they afford so many of these stupid latex suits? There's no way they could be cheap.

“Uuuuh… Am I in fucking… I dunno, hidden camera kind of thing? Cause it ain’t funny…” He says, visibly nervous and somewhat scared, keeping his distance from the suit
Did the suit move just now? It couldn't be. Maybe Pewnys fear of Griffons was getting to him.

He shudders “I think I’m just going to… close this chest, move it outside and set it on fire. Yes… That sounds good”
There it was again. That damn suit and stalkings. The suits face had a smile that looked cute and innocent depending on the angle you looked at it.

He shudders “Cute and innocent my ass, all griffons are evil. And no, Vindicar doesn’t count, he is a hippogryph” He adds as if someone was listening, except knowing nobody does.
The next day Pewny wakes up to find a chest sitting in his bedroom.

He looks at the chest and blinks “… And this is why I don’t trust griffons” he says and carefully opens the chest, hoping that the contents won’t be that latex suit.
Treasure Chest Opened! You acquired: a set of action figures of several ponies you know (including a set of weapons for a hippogriff knight figurine).

He gasps in surprise “Now this… wow, just wow. Who even made those? I mean, this looks just like V in his armor…”
The costume chest just sat there, menacingly.

“Hahaha… haha… ha…” He nope’s the HELL out of there.
Something about the costume seemed, off. Perhaps there was more to it than meets the eye?

He shrugs and puts the costume away “I don’t trust this… latex and griffons put together, that just doesn’t sound… safe”
Treasure Chest Opened You Acquired a latex Griffon costume and a pair of black latex stalkings.

He blinks “Now this has to be the WEIRDEST thing I found so far…”
Treasure Chest Opened! You Acquired: an animatronic changeling!

He pokes the animatronic “They have mechanical bugs now? I wonder if it can shapeshift… Or if it even WORKS”
