535: Creatures & Cryptid Files Vol 1: Bigfoot, Loch Ness Monster, and El Chupacabra

Cryptids have captured our curiosity for ages. Tales of mysterious and elusive creatures roaming the wilderness spark our imagination.
In this first installment of... quite a few, we explore three famous cryptids that have left big footprints on popular culture (ahem).
Bigfoot sightings go back centuries. We investigate theories on Gigantopithecus, hear (and see) compelling accounts from seemingly credible witnesses. And, of course, we'll discuss the famous Patterson-Gimlin Film.
The Loch Ness Monster. One of my personal favorites. There are photographs, film and video. Could Nessie be the last surviving dinosaur?
The Chupacabra. Starting in 1995, this vampiric predator terrorized Puerto Rico, massacring livestock. Theories on alien experiments and genetic mutations attempt to explain its sudden appearance.
