As of now, all primals that have extreme fights also have a pony drop, except moggle.

While the reason behind this is unknown, there is still time to add said mount. It could be a bright pink body with red mane horse, and have the musical notes effect (like the i95 mog weapons) on the hooves.

I am sure many people would love having said horse and to make it better, it would give reasons to farm mog extreme, which is a requirement for doing Ramuh Ex.

Please think about it, there are a lot of pink lovers in Eorzea, I know quite a few.
