Summary Rudi and Trudi are flying when Rudi spots something shiny. Suddenly the pair find themselves falling through red fog. They land and hit the ground. Once the fog clears they realise that they are inside a mountain. Rudi tries to fly them up and out but it is impossible to fly through the fog. The only other way out is to go down. As they set off they are nearly run over by a bolder and Rudi becomes trapped inside the mountain. Trudi frees him but ends up swapping places inside the mountain. They realise that someone doesn't want them to be there. Once they are free they hear a voice in the distance and are determined to find out what is going on. At the bottom of the hole they discover a gold mine where they spy a shadow of a scary beast who is guarding the mine. They are taken to the goblin chief who tricks them and ends up chaining them up along with a gang of goblin slaves, who are imprisoned working the mine. Rudi and Trudi decide to try their chances and escape. The goblin slaves decide that they want to join them. They create a diversion and Rudi and Trudi sneak past the guards. When Rudi and Trudi find the "beast" they discover that it is merely a shadow puppet and a loud speaker. The goblin slaves rebel and go after the goblin chief, capturing him. At that moment the mountain starts to shake. Rudi grabs some gold and runs out. Rudi passes the gold on to the goblin slaves and the two friends make their way back to the skies.
