Hello people this is how I got my own pachyrinosaurus.So I checked the info about this dino and I read that their torpor drops pretty quick. So off I went to find some cnidaria.After that I had a bunch of bio toxin and alot of mejoberries.Then i went to find a pachyrinosaurus with my pulmonoscorpius (Barb) and then the search begins.I found one that is alone and I mounted on Barb.Then i hit the pachyrinosaurus using barb.I hit it a few times and then it went to sleep.Then i dismounted off Barb and fed the pachyrinosaurus some mejoberries while feeding it bio toxin when the torpor drops.After a while it was my pet!!! (Warning I hit the pachyrinosaurus using Barb until it was low health until it went unconscious so beware.In my first attempt a random titanomyrma come in and killed it... The pachyrinosaurus also spawns at dangerous places too so be careful) Sorry if this was long😅 I hope you get a pachyrinosaurus soon if your looking for one.
