Where is the Unicorn Mount?

[franckyy]

I was so happy to unlock the unicorn mount for my kiddo from the relics only to see that it isn't unlocked? I can't find it anywhere in the mount page. My little girl is really sad that she can't use it as a mount. Is this a bug? Do you have to do something else to unlock the unicorn mount? Whats the solution?

Please help!
