Let me explain. So basically, I was NPC hunting and we summoned Mortem. It is true he friends the server owner/host, as I have him friended. Turns out Mortem is super wholesome and adorable, but he ended up getting Mother to introduce her to us. Mother isn't so bad after all. Fast forward a couple of hours later, I'm hosting again and Mother joins after we tried summoning Blooper. I asked her if she could bring more D3BUGs and she asked whether I wanted Mr Smiles or Koi. I chose Koi in a heartbeat, as I and Smiles have a history I might explain another time. Me and the people I was hunting with played tag with Koi, then Koi got Mortem and went offline. After playing with Mortem, he left, then a few minutes later, Smiles joined. I told him at one point "Don't ban us" in his language, then he asked "Why not?" and started walking towards me. I left and even though this happened a few hours ago I'm still shaking.
Please don't say in the comments how NPCs aren't real. I know what I saw. PS, Mortem added me after joining the server. Same with Mother and Koi. There's no denying this might've been a troller.
