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.
HLN-A says in on scorched earth that magmasaurs were tested on scorched earth and the dossier says jerboas are not really jerboas they are something else so maybe Feroxes
were tested on scorched too and the jerboas actually evolved from a few ferox
left behind by accident? (Just a theory)
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.
When youre in the ferox cave beware of bears A LOT OF BEARS luckily theyre stuck there like almost any creature in the cave so pick something for long range. (You can go through most of the cave with even a dragon but u need a cryopod)
