Drive the Jeep to the herder's brother's farm (right side star on the map). The fur is on the fence to the left of the chicken coop.
(Although you also need the bolt cutters from the upper left star, you must eventually take the fur back for DNA testing before you can finish Puerto Rico.)
You find it caught on the fence of the farmer's brother.
Run the fur through the DNA analysis, but you find that it is only coyote fur. You will have to go back to Puerto Rico to find more evidence.
During the DNA testing on Cryptids Island, you will add the sample (fur or egg shells) to a beaker, then before add an enzyme (the red #3). Before putting this mixture into the tray, you add Lab Gel, which is yellow in color, to the tray. When you add the orange sample beaker, the tray also turns orange.
You get the fur from a fence in Puerto Rico. Back at the lab, you run a DNA test, but it turns out to be ordinary coyote fur.
At the herder's brother's house (right side star), there is fur on the fence at the chicken coop. You simply take it.
You place one of the samples (fur or egg shells) in a vial and follow the instructions on the right side of the screen. When the x-ray grid is in the developer, push the flashing button.
You don't. The only fur is the possible chupacabra fur on the fence at Puerto Rico. All you get from your trip to the Himalayas is a lantern and a photo of a footprint in the snow.
In Puerto Rico, deliver some feed to the farmer's brother (right side star). There is some fur on the fence at the chicken coop.
Once you have a fur sample from the brother's farm in Puerto Rico, take it back to the Mews lab for DNA testing. Select it from your items to start the test, and follow the instructions. After you move ONLY the x-ray screen into the developer, press the button to see if it worked. You can try as many times as you need to. If you are successful, Mews tells you the result.
The proof is at each of the locations, but there is some less-than-convincing evidence. You get a photo of Nessie at Loch Ness that is faked, and another one that is a movie prop. But you finally get a real photo. You find some fur on your first visit to Puerto Rico that turns out to be coyote fur, but you return to trap the chupacabra. You find a footprint in the snow in the Himalayas that is unconvincing, but when the three other cryptids are proven, you get to hunt for Bigfoot instead.
There do not appear to be any sheep anywhere on Cryptids Island. There are many goats at the Puerto Rico location, and part of the plan to catch the chupacabra involves using them as bait. After first testing the fur from the barbed wire fence, return to Puerto Rico to use the jeep to corral the three spotted goats at Snaggletooth Rock.
At the Mews lab, select a sample from your item bag, and the DNA test will start. Follow the instructions carefully and don't spill anything. When you have the tray completed, move ONLY the x-ray screen into the Developer and press the button. If you are successful, Mews will give you the results.
