I'm tellin you, I've tried so many things and still cant figure out what to do, I have sold eggs, merged them, used them in specific events. named pets crazy things, I legitamately don't know what to do anymore.
For the egg, I think I broke a bit from trying things before it so that might be why, but the new ghost smith event can effect eggs and make them mergable and upgradable, can't use it on the ground anymore though
EDIT: you said that getting the new thing didn't require any items, does that include food and such? or just equippable
