This little monsters spawn ( lost island) at the aberration/artifact of the strong cave, not sure if they can be tamed as I have not tried it yet, the cave is at the north of the island behind a waterfall, coordinates on gps being 26.6 54.5
For me this thing in cute form almost looks like Jerboa, if he eats element and you are low lvl. Turn around and RUN AS FAST AS YOUR LEGS CAN GO (Or jump onto parasaur or galimimus) Otherwise this creature is super cool.
Right next to where you accept the Mission "Searching the Fro-Zone" is the entrance to a cave with alot of Feroxes in it. It also contains Polar Bears though so bring good Armor And Weapons and Potentialy a good Dino. A smaller one is better though since the Feroxes will run towards you to get the element your holding and might get caught in the crossfire if you fight the Polar Bears with a large Dino.
Has anyone ever run into duplicating the Ferox while trying to tame it? As in you feed it right after it transforms and it runs off while you hear a Ferox transform(sounds like it's under the map) and when it's done you suddenly have 2 Ferox's at the same lvl, sex & tame percentage? I'm not complaining or anything but it caught me off guard, as example when I got to the cave on Fjordur, there was 2 lvl 50's, 1 lvl 180 & a lvl 200, I killed of the lvl 50's and not I have 1 lvl 180 & 3 lvl 200's being tamed lol
