You can revive pets at the starting town all you have to do is go to the girl statue that has red eyes near the pet stable (where you see pets walking around in a fenced area) and if you want to get new pets you must get eggs and go to the stable in the starting area and wait for them to hatch. good luck
@thethirdiii I've got all the pets instead of the healing Skull Pixie...How can I get it??? Someone says the only way is to get the premiun edition....
The premium edition isn't hard to get, its free. But you will need to restart your progress or finish the game without the healer. Click on the premium edition at the main menu and when you start the game, in the premium part of the inventory there will be a bunch of equipment and a skull pixie egg. Oh well, guess that's it :P
