Peachtot

Peachtot? when you hear that name you wouldn't think of something scary rather something sweet but the experience i had during my time in this world was not as sweet and pleasant as the name of the one causing this fear
while playing i didn't notice anything off about the world just seemed so normal to me but while i was exploring and gathering resources for days i felt watched but couldn't really tell why it is i felt that i started to experience anxiety while playing and that is when i started seeing the Player called Peachtot in my single player world at first i thought someone was trolling me and somehow made my single player world online or a type of Lan but who?
But as time went on i started to figure out that this "Player" was in the world even tho Lan wasn't on... i Felt terrified to my core what is this what am i seeing i said to myself wondering what to do being to afraid to leave and not catch evidence that i'm not losing my mind i was determined to beat this world and find out what was watching me so i kept playing for days, weeks even a month as a normal world would be played while trying gather everything i could recording such a long time of gameplay would be severe so i took images instead all the times i noticed it i quickly took a picture
after examining the pictures closely to see what it is i found out that is looks like Alex but with red eyes and something on it's mouth and head the first image i took looked abit funny like i thought alex was walking sideways but i soon realised that it has multiple arms and legs i felt terrified to play but i kept going and going that is when i started to hear faint crying through my audio i thought it was in real life but when i took off the headset the crying was gone but each time i put it back on it comes back.
it hasn't harmed me in any way it just stares at me watching me but for what reason is it watching to learn or something darker
the only information i could find about the user called "Peachtot" was their a player a existing account but their account doesn't seem to be having the "Skin" of the beast i saw is the player just using the Username or is the Creature somehow stealing their Player Data and then becoming them 
my World ended with me seeing randomly summoned into Netherworld above bedrock being unable to Starve,build or even Die to escape back to the overworld and that was the end of my world
