Grandpa used to be quite a wild one. And strong, too.
He could lift a hundred tree trunks at once.
When Ryan’s Grandpa was young, he was an extremely tough and strong rhinoceros. But now he is old. He prefers to doze all day in the shade.
Ryan, of course, is not happy about that; he wants to play and run around. While Grandpa is asleep, Ryan sneaks off to the waterfall in search of adventure. That is quite a dangerous place for a little rhino.
And then the inevitable happens: Ryan falls. Fortunately, he gets stuck midway down, but he cannot get back up! The animals that rush to the rescue are unable to help him either. There is only one who can: Ryan’s tough, strong grandpa.
