A miner and his friends get stuck in a mineshaft. Will they be able to get out?

Ralph, Melvin, and Garen have been mining for years together. They always return home safely, but this time, two of them are trapped by boulders. Dynamite won't help, so maybe a few explosive monsters could do the trick...mix in a river with a waterfall and the discovery of a valuable treasure, and this diary can be a lot of fun to hear!
