Some zooform phenomena, like Wolfie, seem so bizarre that they defy belief, let alone categorisation, yet their eyewitnesses vehemently affirm that they were real. Another notable example is the entity that Godfrey H. Anderson claimed to have spied on 23 November 1904 while walking along a street in Edinburgh, Scotland. Suddenly, he saw a grotesque 'something' rise out of the gutter and spring up at the throat of a horse. According to Anderson's description, cited in Creatures of the Outer Edge (1978) by Jerome Clark and Loren Coleman, the horse's weird attacker was:
"[a] vague black shape about four feet long and two and a half feet high...[it was shaped] like an hourglass and moved like a huge caterpillar."
The horse reared up in terror, and as it did so its assailant vanished.
