*I received a copy of this book in exchange for an honest review*
This was an okay book to teach children that bullying is wrong and to teach respect. I thought it was written well, even if a bit preachy-sounding at times. While the pictures were great, and my (under 3 year-old) kids loved them, the language was a bit formal and they had difficulty understanding some of the words, and they lost interest in the book as a result. I also would have loved to have more reasons as to why bullying was bad, like having the fish explain how bullying hurts and why it's wrong. The only reason in the book as to why you shouldn't be a bully is basically that what comes around, goes around, so don't be a bully because there's always bigger bullies in the sea. The only reasons the bullies stopped bullying in the book was because they then were bullied, or were scared of being bullied, which in my opinion, isn't a very good or truly effective message. I was bullied as a child, and I had teachers that tried using this message to get them to stop, and while it worked for a while, they would just go back to their bullying ways a few days later.
All in all, this was an okay book, but it's not worth the price to me. If you're interested in the Hugo books, I would definitely recommend reading one of the other Hugo books instead of this one.
