That's something I've seen on different servers and I'm wondering if we can add it here the only issue I see with it is it might effect with the /pet that we have already I really like the idea of making a parrot farm or something like that
I'd love to use /gem to buy a special pet-egg that is like a container. It can be a one use only.. You pick up a mob with it, and then when you rename it and place it, the special egg disappears, but instead, .. you have a pet. It would be nice if that's possible
Another way to have tradable pets using the current /pets system is a transfer button that opens a gui with heads, we click on the head and the pet appears in their /pets gui as a new pet if they dont have one already.
