Bakabu, the earworm, is known to many children from the songbook series "Listen Up, Bakabu." But no one really knows how things are at home for Bakabu in the mysterious Singing Land or what it looks like. Until now. "Bakabu and the Golden Note Key" is the first story about the little blue earworm from the village of Hornhausen, and it features a real adventure for him. Fortunately, his friends Jack Embalo, the grumpy mule, Ukuleila, the shrill cricket, Uncle Cornet, the old ear shell, and of course Charlie Gru, the clay pigeon, are there to help him with advice and support.

From the content: Bakabu has the honor of opening the grand singing festival with the golden note key. Tragically, however, he loses it due to a strong gust of wind. The wind carries the note key to the legendary Thunder Island in the terrible Thunder Sea.
