The Hippo Charges the Chest on the Left or Right

You can even have your hippo rush up and knock one of the chests open if you wanted him to. Roll a D20 plus five to make sure your hippo can hit that chest with full speed at his weakest spot. As long as you can get a eight or higher, you break enough of the lid to reach into the chest. You think there's a thousand gold pieces worth of treasure inside of that chest. But so far the hippo has used his turn.
