The mockumentary opens with the line: “In the summer of 2010, Pleasantview witnessed a series of killings no one could explain... except the children.” Over a span of two weeks, five Sims are found dead under eerie and impossible circumstances — strangled in locked rooms, drowned in empty pools, or simply vanished. All the victims had previously reported seeing “the pink one” — a term children use for the elusive, silent figure known as the Social Bunny.
