A bull in a bullpen is being a bully to other bulls and smaller animals like chickens, rabbits, and pigs.  When another animal steps up and calls him a bully, he realizes the error of his ways and begins acting nicely towards others.

A very simplistic story, the title character has an abrupt change after the goat calls him "bully".  But no accompanying text or illustrations explains what is going on in the bull's mind.  Why is it bad to be a bully?  How does it feel to be called a bully?  It's not very well explained.  At least the change comes from the identification of the problem.  If this book teaches one thing: it's that a bully should be told when they are acting like one.
