You are able to buy these eggs as pets, for 5 Galleons each.
Once they are sold, they are sold...
You can however still look at the pets in the shop.
I hope you enjoy the pets. There will be new ones every month.
I ask you to remember that they are not my own invention and that the actual eggs or later pets are not linked to the inventor. There is however an egg in the shop which is not for sale and acts as a direct owl service to the inventor.
