Honey Pie Pony is feeling left out of all the kids' play. She's the only one with four legs. There's no one like her to talk to and share her feelings. So Strawberry and the others take Honey Pie to Ice Cream Island - a land of horses - where she meets other ponies.

There's someone...or something strange in the neighborhood and the kids imagine the worst - but Strawberry finds it's a new girl, Blueberry Muffin, and she's just like them.
