If you find yourself against a herd of these, just keep backing up and using your boomerangs, trans arrows, and slingshots. Both the primary and secondary attacks have a delay before they actually deal damage, and they have to stop moving first, so if you keep backpedaling they won't be able to hit you.
In a group they attack, individual they run. Pick the lone wolf and lead it by facing the way you want it to go and trap it against a wall or rock or a safe place. No missed shots, no wasted resources, and a easy Morrelatops tame.
To tame it just boomerang it by throwing. Tamed a lvl 2 and 7 this way at low lvl. Just find a lone one and then aim for the head first. As it’s running boom it some more. If u see another morell but it’s kinda far I found that the paras danger Since wave is a good Indication if it’s far enough or not.
Only creature that I know of that can drink. I thought u just could use cactus sap for water but one day I dismounted mine in shallow water and she drank like a thirsty camel. I have two and I take them everywhere now.
