to do the RAM attack all of you have to do is run and it will start to speed up like a dire bears and run into your enemies/creatures with your woolly rhino and when it the horn is near the enemies, TAP the ATTACK button and there you go it deal massive damage, i don't recommend doing that to a brontosaurus tho (sorry for my bad english)
There creatures are almost entirely passive, so long as you don't attack them. If you do aggro one (to kill it for either it's great pelt supplies or it's horn), it is best to get on top of a small cliff or something like that. Running away is almost always futile, as not only do they move faster the longer they charge at you, they do up to 10 times as much damage. If you are to run, don't run straight, unless you'd like to be a rhino's horn decoration.
These rhinos might be endangered But they are actually keeping their number from 300 to 2050 At my guess they’re actually strong whenever I met my first one I thought it was a big deer wolf and they’re easy to kill so I tried to kill it and till I saw its face that’s why I knew it was a white rhino and then I was like OH CRAP and then one charged me and it was a level 200! I recommend you take them for PVP and if The person you’re reading has Tourette’s Bring some stegosaurs because they are good against Tourette’s
