Yona Yak is a yak. Yaks have a bad sense of direction, so when Yona gets lost in Ponyville, she needs some help getting back to the School of Friendship. Unfortunately, that means getting the attention of somepony who can understand her, and she learns that not everypony gets her as well as her friends at the School of Friendship do. But if Yona cannot get home, she will starve, and she will not let that happen. Luckily, she encounters members of the Mane Six along the way, so she is in luck.
