The big spotted goat pile doesn't do anything. Sorry, it's just there for decoration! :)
Once you herd the 3 spotted goats into the area at Snaggletooth Rock, get out of the jeep and join the farmer who has prepared a trap.
talk to the farmer in the top left corner and them drive over three spotted goats
You go in to the truck and chase three spotted goats into a curved bones or rock i don't know what it is but that's what you do.
The chupacabra is said to prefer spotted goats, so corral some on your second trip to Puerto Rico (the first time you only get fur). When you have 3 spotted goats in the area at the center star, Snaggletooth Rock, get out to join the farmer, who has a trap prepared.
There are lots of goats at Puerto Rico, but no mountain goats.
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.
On your second trip to Puerto Rico (the first time you get the fur), drive the jeep to herd 3 spotted goats into the place the chupacabra was spotted, the rocks at the center star. Then get out and meet the farmer, who has prepared a trap.
You have to herd them one at a time. There are a lot of them right by the place you need to set the trap. It can take a long time, but you can do it! Remember to herd only spotted ones.
You don't take any goats from Puerto Rico. On your second trip there, the farmer prepares a trap for the chupacabra. Drive your jeep to corral 3 spotted goats into the area of Snaggletooth Rock (center star on the map). Then get out and join the farmer there.
The three spotted goats at Snaggletooth Rock (center star) are going to be bait for the chupacabra. On your first trip to Puerto Rico, get the fur from the fence at the chicken farm and take it back to the mews lab for DNA testing. When you return to Puerto Rico, the goat herder is setting a trap for the chupacabra at Snaggletooth Rock. Use the jeep to chase three spotted goats into the grassy area there, then join the herder to wait for the chupacabra.
After you take the fur from the fence back to Mews, come back to Puerto Rico and steer the jeep to corral 3 spotted goats at Snaggletooth Rock (the center star on the map). Once you have 3 in the center, get out of the jeep there and go to meet the farmer.
