Yellowstone

He'll join your breeding farm once you've sent a horse aged 25 or more to heaven.

Yggdrasil is a special horse that ages every time you send a horse aged 25 or more to heaven.

As he gets older, his appearance changes! After the very first change of appearance, a photo album becomes available so you can look at the horse's previous looks.

Every time he changes his appearance, a gift appears in your profile page.

When he reaches his last transformation, you can rejuvenate him to the age of a few hours.

Yellowstone cannot be sold.
