In the 'ghost pony story', the central character is most likely the ghost pony. However, there could be other supporting characters. There might be a wise old owl that gives advice about the ghost pony. There could be a group of curious squirrels that are always watching the ghost pony's antics. And of course, if the story is set on a farm, there could be the farmer and his family. The farmer might be initially scared of the ghost pony but then come to understand it. His children could be the ones who befriend the ghost pony and try to solve the mystery of why it's still around as a ghost.
Well, if the 'ghost pony story' is about a pony that has become a ghost, then obviously the ghost pony is a main character.
