Unfortunately, master wallpaperer Lupo has absolutely no idea about wallpapering and painting and soon things get chaotic.

Everyone is practicing in the big dance competition. When the time comes, Lupo tries some illegal tricks again. Is he smarter than Fix and Foxi and Lupinchen together? Papa invites an old school friend who's come a long way to dinner. He asks his family to behave in an exemplary manner to impress his old friend at least a little.
