You see there was a time when Rhino didn't charge and he couldn't see very well at all. Poor old Rhino really wanted to be invited to the Dance of the Horns up on the plains with Buffalo and all the other horned animals. But Rhino didn't have a horn, so he wasn't allowed. The Monkeys decided to help Rhino and made him a horn from a piece of old wood. But when Rhino woke up, he didn't know what it was. 'Aargh! Thing on the end of my nose! CHAAaarge!' And that's why Rhino charges.
