Rarity takes Sweetie Belle to the Everfree Forest to correct a mistake and teach her a lesson on pet care.
This was written for an internet writing group using the theme "pet stuck in a tree". One of the suggestions for a starting situation was this: "Opalescence is stuck in a tree in the Everfree Forest and Rarity must deal with a pack of tree bound monkeys wearing dirty rags to get her pet back."
I'm so glad I'm not the only one who thought Sweetie might end up going that general direction. Didn't see it coming until you mentioned Scootaloo.
