Already alone the initial story is nice, especially since the block mountain is not the only family where the mother is annoyed from time to time about the dear family.
The story culminates of a funny incident to the next. The character are all adorable (though a little extravagant) and it's funny mitanzuhören how Bibi and Bernard always have new ideas that might like Barbara.
A story that is fun from start to finish and is highly recommended.
