The adoption agency on Atebus always says there are 0 left. Are they ever available there?

It is announced in the news when they are but you can also use an elixir to change one pet into either of those species.

Ok, thanks! I didn't know there were elixirs, lol.

There's also and its other colors for Cadogres. Much cheaper than buying the elixir.

Thanks for the info, :)
