A chupacabra would be more exciting?
There are long-ago anecdotal records of the ‘Thunderbird’ - even of it taking babies and animals. It’s become mythic in some North American cultures.
(Chupacabra will have to age far beyond its first recorded sighting in 1995 for me to buy into it.)
But who knows? There are all sorts of whangdoodles and snallygasters out there; and they certainly make life more fun and interesting.
