A pony called Casper
A group of friends are riding near a supposedly 'haunted' house when they here a muffled whinny from behind a stable. They dare each other to go check out the 'ghost horse'
A pony called Popcorn (Name not fully decided yet)
A rich girl finds her pony Popcorn too old and boring, and sells him to a younger girl and buys a Thoroughbred instead.
Turns out it was the worst mistake she could make show-horse wise!
A pony called Kiante (Based on a true story)
I have't given much thaught to this one but its about a young girl and the bond she has with her pony
This is all I have come up with but hopefully more ideas will come!!
