Every evening, Jan and Henry try to fall asleep, but they are repeatedly disturbed by a strange noise: sometimes it's a whistle, sometimes a croak, or a squeak. The two meerkat brothers come up with all sorts of crazy ideas about where the noise could be coming from. This leads to the most imaginative stories, and a squeaky door, for example, turns into a grandma in knight's armor who is cooking pudding. Even the littlest ones can join in the guessing and explore with the meerkats what the source of the whistling, croaking, or squeaking is. The funniest Jan & Henry stories from the series!.
