Listen carefully! With this beautiful listening and memory game of The Rupsje Nooitgenoeg, the goal is to recognize different sounds and give them a name. By shaking the wooden cylinders and listening carefully, children can determine which two cylinders belong together. The weight can also help! With the viewing window at the bottom, the contents can be easily compared. Who will manage to collect the most pairs? The cylinders are 4 centimeters high.
