A sloath
A sloath is like a ghost, but lazier. They don’t leave clues. They just show up, and you’re gone. No mess. No noise. Just a dead body and a lot of regrets.
My friend disappeared after he told a sloath he was going to be late.
My mom’s sloath came in through the fridge and took her out for not having snacks.
My brother got eaten by a sloath for not doing his chores.
