Hui Buh - Das Schlossgespenst

In the 14th century, Ritter Balduin is found dead by a lightning strike, transforming him into the castle ghost Hui Buh. 500 years later, Hui Buh is the only ghost allowed to haunt Schloss Burgeck, but when a new king, Julius, arrives, he loses his ability to scare and must get recertified. With the help of the Kastellan, Hui Buh tries to scare off King Julius, but his efforts backfire. Hui Buh must then join forces with the king to find a treasure that can only be accessed from the inside, all while navigating a series of challenges to regain his ghostly license.
