Fishy's Magic Horses Texture Pack

Fishy's Magic Horses adds some interesting changes to horses. With this pack installed, white horses that spawn in a dark forest biome will have a 10% chance to spawn as a unicorn. Alternatively, you can rename a white horse to "unicorn" to change it. Renaming a horse "Pegasus" will turn it into a Pegasus, a horse with wings. Renaming a horse "Zorse" will convert it into a zombie horse. Moreover, donkeys and mules can be renamed "Skelly" to convert them into their skeleton variants.

Take a look at the screenshots to see what you can expect from this pack. Download links are given below. Read the installation instructions carefully.
