According to skeptic Joe Nickell, "perhaps the world's only full-time salaried paranormal investigator," Bigfoot sightings showed a greater variation before the Patterson film of 1967; after that a kind of cultural consensus emerged about what Bigfoot should look like. And his investigation of the distribution of North American lake monster sightings showed a nearly perfect match for the distribution of the common otter, which when three of four are seen swimming in a straight line look remarkably serpentine. But read on, as there's much more from--as some people accuse him of being--the destroyer of the sense of wonder in the world. Loren Coleman replies to Nickel's critiques of matters cryptozoological in Bigfoot Is Man In Suit: Nickell’s Old Argument. We're sure that Nickel would also have an explanation for the infamous malevolent "witch" capable of transforming itself into a wolf, coyote, bear, bird, or any other animal, as detailed inSkinwalker Chronicles IV. But there is no doubt about the answer to this question: Chupacabras in Spain? It's a mummified mongoose.
