It’s another dull day in Mullewapp, and Waldemar the hog, Franz von Hahn and Johnny Mauser do not know what to do with themselves. High time for a real adventure! The three friends grab their bikes and cycle all around the world – a princess needs their help, a treasure is waiting to be unearthed, and they have a narrow escape from a cannibal. But with the help of Jumbo the elephant they still make it home in time for dinner.
