Haba heroes of the moonlight

It won't be a peaceful night! In the moonlight, wizard Zirroz magically floats all the gems out of the castle. To stop him, the kids sneak very cleverly through the castle garden and collect all kinds of colored pebbles. At the right time, they can exchange them for the stolen treasures unnoticed. But beware: the colors must match, otherwise the plan will not work! Whoever saves the most gems wins the game!
