Derpy is often made fun of; she puts on a brave face and is able to get through her life without letting it get to her; until one day she is forced to put everything she has learned from Rainbow Dash about bullies into practice. Will Derpy be able to stand up to the bullies; and what is with this note she has received from Rainbow Dash? Is Derpy's time in Ponyville over; or is this the day something truly amazing is going to happen in her life.
