Mus's cousins arrive in the Blue Forest. It's not just a simple visit: they want to stay and live there! They used to live in the city, in a park, but the city council is doing construction work there and they have become homeless.
The cousins are welcome in the forest but they are noisy and untidy, and it soon becomes clear that it is impossible to live with them. Should they stay or should they go? What shall Bitmax & Co do with the cousins?
An invitation to hospitality and empathy!
