It is night in Wimmlingen. People and animals are sleeping - at least some of them. Andrea can't fall asleep because Thomas is still showering on the floor above her. In contrast, Niko is peacefully dozing under a cloth in his birdcage. Outside, bats are fluttering around and a hedgehog is snuffling through the grass. In the cultural center, there is a reading night in the library, and on the ground floor, the terrariums of the reptile exhibition shimmer with a greenish hue. The night train is ready at the station. Even though there aren't as many people out at night, there's still a lot happening on this warm summer night in Wimmlingen. A burglar is taking advantage of the darkness to break into the dental practice. Will he be able to escape unnoticed? The highlight and conclusion of this very special Wimmel adventure is the park festival with fireworks. Countless details make this atmospheric night book the perfect bedtime reading for little and big Wimmel fans. Recommended for children aged 2 to 6 years.
