Episode Title:Airlift.Episode Description:David meets up with his friend Cosmo, who says he is worried about the bats in the forest. Cosmo says the humans are poisoning the insects the bats eat, and many of them are starving. The bats are currently hibernating in trees, which are in danger of being cut down. David calls on all the gnomes in the forest to make baskets from bullrushes, and then the bats are put into the baskets. A flock of geese transports the bats to a gnome-operated animal hospital when they can finish hibernating.
