Actually, that might help. The sludge spirit — Lucky, it told me that it used to live in a laundromat. The laundromat closed down, and after that, Father told it that it could come here.

The most interesting part, though, is that Lucky didn't originally feed on fear. It hasn't attacked anyone else because it's been eating dirty water instead. Whatever caused it to change wore off once Kakuya's game ended... It sounds like Slimy is probably in the same situation, if you were able to talk peacefully this time.
