Bibi and Marita and Moni are dropped at the beginning of the story when dodgeball always first and by twin brothers geärgert.Dann they speak in their new Geheimsprachen.Doch because the two guys they want to eavesdrop again lure the boy into a trap and scare them. And they speak in 2 different Sprachen.Die secret languages to understand is very difficult, too heavy not empfehlenswert.Und certainly not for kindergarteners and elementary school students understand the Geheimsprachen.Geld waste.
