I had one that I got at the beginning, not the first one, and named it stoner..why because it would carry all my stone and almost never move hence the name stoner. I had him for a long time. I once lost it after a fight and found it and a do not remember what it fought, with all my tames(had a least 4 raptors), and it died...RIP... that time I had another one named stoner2(because the other one could not carry any more stone) it died later one now i have one named stoner3 and is like a crate(any creature for me is a crate) and is now in my house the only lystrosaurus of mine that died where the stoner one and one random one Do Not NAME them stoner they WILL die stoner3 has there implants and carries on the stoner legacy.
