Pixie Fix lives in the Evergreen Forest, in the trunk of a 1000 years old pedunculate oak tree. He loves to prepare all sorts of medicines, magic potions, and special elixirs in his laboratory. His most important potion is the Mantha of Light which is made of dewdrops and the juice of the old oak tree. A sudden event changes their lives entirely: one morning they cannot find any dewdrops. Pixie Fix decides to unravel the mystery of the missing dewdrops. At dawn he sets out on a journey along with the fire-fly Sizzle to find the dewdrops. Travelling along the roots of the 1000-year-old tree, they meet a tricky toad, Lupo who only allows them to pass when Pixie takes part in his games.
