De Li stands on a box to reach some plumatoes on a tree. Having picked the fruit, she takes the box to her pod, but when she gets back from Yogo the box has gone! It turns out that each Pipling is borrowing the box for his or her own needs. They each take it, not realising that they're depriving the others of it. When the children arrive, they help by taking it to each Pipling. De Li realises that they can all use the box as long as they work together.
