That is ones own opinoin. There is no scientific evidence.
After you have the chupacabra tooth, you still need to prove that Nessie and the Jersey Devil exist. (The monks are stubborn about the Yeti and your snow footprint is unconvincing.) Get the photo of Nessie, and some egg shells from the Jersey Devil, and then you can pursue Bigfoot instead of the Yeti. (see related questions)
yes there are only 8 in existence
You have to look for Bigfoot/Yeti in the Himalayas, the Jersey Devil in New Jersey, the Loch Ness Monster in the Loch Ness in Scotland and the Chupacabra in Puerto Rico.
There are 3 you have to prove: Nessie (Loch Ness) Chupacabra (Puerto Rico) New Jersey Devil (New Jersey) You can't get what you need to prove the Yeti, so you are sent to find Bigfoot.
Run the DNA test on the eggshells to prove the existence of the Jersey Devil. You will also need to prove Nessie and the chupacabra, and bring back the photo of the footprint from the top of the mountain in the Himalayas. When all but the Yeti are proven (Nessie, chupacabra, and the Jersey Devil), Mews will send you after the Bigfoot in the Pacific Northwest.
You still have to prove the chupacabra and the Jersey Devil. You can get a photo from the Himalayas, but it does not prove the Yeti. So when you have the other three proven, you will be sent to chase Bigfoot in the Northwest.
You don't. After you get the lantern and the footprint photo, there is no other proof available in the Himalayas. Once you prove the other three (Nessie, Chupacabra, and Jersey Devil), an opportunity will come up to chase Bigfoot instead of the Yeti, since they are similar creatures.
1666 the jersey devil was born
You don't. Other than the lantern and the footprint photo, there is nothing to do at the Himalayas. Later, when you have proved the existence of the other three cryptids (Nessie, Chupacabra and the Jersey Devil), Mews will send you to the Pacific Northwest to find Bigfoot, which is much the same creature as the Yeti.
no the jersey devils only lived in new jersey that is why it is called the JERSEY devil.
there are many ways the jersey devil is presented. in fact different people telling different stories can give the jersey devil different appearances
The answer is no. When the Jersey Devil was born, a man shot a cannonball at it, but the Devil kept on flying.
