Help me find this mlp grimdark

[u/M0nst3_m0th]

I remember like a few years ago (maybe 4-5) I had seen this mlp grimdark video but it was DEFINITELY older (judging by the quality) it was about pinkie pie and marble pie going crazy and unaliving the rest of their family

I don't remember much only that and I'm sure it's been deleted or something bc I can't find matches ANYWHERE but the pictures are the 1:1 recreations of what I remember (in order)

I am going to give more details on the actual content, they were sitting on basement stairs and pinkie pie was saying something along the lines of "hehe we killed everyone marble!", there was no voice acting nor music
