My Little Pony comic #26, “Happy Harvest!”
Summary: Cotton Candy unwittingly gave Applejack a magic apple as a birthday present … but now Applejack will sleep for a hundred years unless the ponies can get into the Garden of Herbs to cure her!
Comments: Poor Cotton Candy, I feel sorry for her as her friends knock her away from the secret passage. Anyway, this is how she becomes the Ponyland nurse, although “herbalist” seems like a more apt name. I’m interested to see the phrase “earth ponies” appear in this comic, I thought that was mostly a show thing.
