Opal is quite popular around the town of Ponyville. She's ripped up a few dresses, scratched some unsuspecting tourists, and gotten herself printed in the paper for the culprit of many disasters. As the pet of Miss Rarity, element of generosity, she's managed to get away with most of what she does.
That doesn't mean the ponies of Ponyville have to like her.
In fact, the residents do anything but like her. Especially a certain filly with the name of Apple Bloom. However, when guilt-tripped into accepting the job of cat-sitting the small beast, many more disasters are about to come. Will she be able to overcome the battle between her and Opal? Or will she be conquered and clawed until she can't bear it anymore? We'll have to see, now won't we?
