Neko Seek is a Fan-Created Character based off a character named Seek from the Roblox game called Doors. Seek appears as a black figure with 1 eye. I see that from Door 20 - 40, Seek spawns in a long hall after eyes start appearing on fall from the previous rooms. Or he doesn't spawn at all... It's happened to me a couple of times. So like... do anything... I don't know... (Couldn't really get a voice to match the character... Best option is to ignore it...)
