|"'Feejee Mermaid' has become the generic term for the many fake mermaids that can be found around the world..."
This article contains information relating to a hoax. According to Cambridge dictionary a hoax is "a plan to deceive a large group of people; a trick."
The Dogigator is a river cryptid that has the appearance of the hybrid of a alligator and a dog. It can be seen in the Abita Mystery House, and also the Anita Mystery House which have a variety of cryptids. One of them is the Dogigator, baptized as "Darrel". The scaly pooch has its own house and food dish, surrounded with plants.
Darrel was confirmed to be a hoax, and is just a statue.
Nothing is known about the biology and habitat of this reptomammalian hybrid (which also happens in another cryptids, such as the Coonigator or Crocodingo). Like the Bassigator, it's sometimes considered a fearsome critter. If it was real, it would probaly be a survivor of the extinct crocodiles, in which some would stand upright like that.
