This thing has the strength of 100000000000 alpha rexes, the colour of a dire wolf and the body of a gigantopithecus. Only option, bola your friend and run, if you don't have anyone, hope you had a good life
DO NOT fight them, they are not tame able, they will kill you and I learned that the hard way. I was feeling powerful so I went into the ice cave knowing it was hard but me and dunklo, my terror bird; he was 364, went in and died. I loved him sooooo much. R.I.P dunklo
On mobile in the strong cave just run past them if u can. U don't have to worry about purlovias or polar bears so just jump and run. On the other hand an easier (but slower) way is to hit option when u see them and quit to menu. Save ur progress in a backup save if u wanna be absolutely safe then return to game. U should find the cave clear or, in the room with the floating ice chunks, mostly clear. I recommend using the second option for your first time since there's at least two crystal patches blocking access to the artifact. After the first run the crystals won't really reappear and you will face a lot fewer animals.
