The big green troll loves treasure. He especially loves multi-colored pebbles and wherever he manages to find them, he takes them and drags them to his cave. But in the Pin Gems Rescue game, he attacked a bunch of treasures, but they were cleverly hidden, securing them with fiery lava and other dangerous barriers. The monster is afraid of both fire and water. Therefore, you must make sure that he cannot touch either one or the other. As a result of your reasonable actions, the jewels should literally fall at the feet of the monster. Move the pins aside and let the stones fall freely down. They should also not come into contact with hot lava. Otherwise, there will be nothing left of them in Pin Gems Rescue.
