Splash! Yet another castle resident has let something fall out of the window and roll into the castle pond: The princess can't find her golden ball, the magician searches for his crystal ball, and the cook has lost a head of cabbage. What will they do? Only Francesco the climbing frog can fetch the items! But he needs help climbing the steep castle tower and tracking down the ball's owner. First, the players open windows to find the right castle resident. Then they help the climbing frog balance the ball up the wall by pulling on the strings — but they need to be careful that the ball doesn't fall into the wrong hole in the wall. The player who uses their skill and memory to return the most balls wins Burg Kletterfrosch.
