SmallyKid90 and SmallyKid91

Hello, my name is bondzab. I've been playing ROBLOX since 2014, and I've seen these two creepy guys on I think Natural Disaster Survival. These two has been creeping me out for the past 3 minutes the round started. These two started saying weird things like "He's here", "We aren't pure", "A little pal" They kept on saying these stuff. They creep me out, so I asked them "What's wrong?" and they said "Free us" and left. And I've never seen them again! In fact, my friend have seen them two more times before they're gone. Their account was pretty recent, they were created the day I posted this. They have been online lately and very active. They don't play anything much apart from Natural Disaster Survival. and I've visited their place, it was very dark and creepy. First off, I see a chair with a Dominus Infernus on it. and when I wander further, I found an NPC named SmallyKid90 and when I come close to it. It started following me. Well that's all I've experienced so far, I'll be updating this as thing goes.
