May Rides a New Pony

When May's pony needs to recover from an injury

She helps her father train a new horse. May's pony, Macaroni, has a sore foot, and she can't ride him for a week or two. But May can't stay away from the stables—she's too pony crazy for that! She decides to help her father train his smart new pony, Zeus, and is so busy that she hardly misses riding Macaroni.

But Macaroni is jealous, and May starts to feel left out herself when her best friends in the Pony Tails seem to forget about her. How can the girls get back into their old groove?
