Petrock Mod (1.19.2, 1.18.2) adds Pet Rocks to Minecraft. It’s very cute and easy. It’s a great addition to any world. You can summon them using paper and an ink bag, and then tame and control them with stoniumore.
There will be no need to walk, feed, bathe, neuter, or groom your pet. Pet Rocks can be trained to sit and stay, and the best part is that your pet rock will never run away.
