Buster is the big fish in a small pond: he is the bully of his fish tank who terrorizes all the smaller fish. But when he gets kicked out and sent to the ocean for his bullying behaviour, a shark bullies him! Buster quickly finds a safe hiding spot and as he catches his breath, he reflects on how it feels to be on the receiving end of a bully’s bashing. So, when Buster sees another little fish in danger of being eaten by the same shark, he comes to the rescue and saves them both. Having gone from bully to bullied to brave, Buster discovers the error of his previous bullying ways and vows to change for the better.

This rhyming picture book shows the perspective of both the bully and the bullied, within the same character, and clearly shows how someone could have a change of heart through experience and empathy.
