Ep 15. Missing Melchior

Melchior sets out for a great meeting of inventors on Diamond Mountain. When he reaches the foot of the mountain, he hears cries for help. When Melchior takes a closer look at the cave, he slips and falls into it himself. But Yanna has already guessed that something has happened to Melchior, and she asks Lapitch and Co. to go and look for him.
