Who's the Boss Rhinoceros?

It's Oliver Rhinoceros's birthday and as a special treat he's going to spend the day watching his boss rhinoceros parents charging around being as bossy as bossy can be. But Oliver doesn't like charging or being bossy and with the support of his Grampa Grumpus, he shows his parents that charging isn't always the answer, particularly in a crisis. Sometimes moving very slowly wins the day.
