The owl goes on holiday

In the forest, the owl is the schoolteacher for all the children. It is fun to teach things. But also tiring. So the owl needs a holiday. The magpie promises to look after the school while he's away. The magpie is very good at building a nest. And at getting everyone to work together. But she is not very good at counting. So she doesn't notice when one of the young mice goes missing.
