Bully was once a heartless, psychopathic black filly fuelled by the pain and humiliation that swelled inside her. And now she's the new filly at school (thanks to a little help from Timidthy). But now not only does she have to make sure not to slip-up. She has to listen to other fillies and colts insults about her. But luckily she has Timidthy to help! But how long can the two keep this up? And who will be the first to realize the new filly isn't who she says she is?
