DAVID tells us about trees: which ones they cut, how they plant new ones and how when every gnome is born a tree is planted. DAVID tells the story of the day they built a birdhouse for the flycatcher. When LISA and DAVID are taking a walk in the forest they receive news that a hunter has captured a flycatcher. With the help of some hamsters, they free all the birds that the hunter has locked up in cages.
