Naya gives Lu and Jo cookies to help them get well, but it seems they might be faking.

The search for buried treasure begins!

Jo is so obsessed with his train that he forgets a promise he made to Naya.

Jo, Naya, and Ludwig are pretending to be Native Americans. They're sneaking around, painting their faces like warriors, and planning to build a teepee.

Jo wants to perform a magic trick, but things don't work out the way he hoped.

Lu is battling a severe case of the hiccups that simply won't go away. Jo and Naya try to help and come up with lots of ideas.

Carmen, the Spanish mouse, now also has an idea to get rid of Lu's hiccups. Will she have more luck and finally be able to help him?

Jo and Naya's plan to give Ludwig a fright to get rid of his hiccups fails, but they accidentally find a method that finally helps. And it's fun too!

Ludwig is all excited because he has been hearing strange noises in the night. Could it be a ghost?

Paul has a hiking day today, so Jo, Naya, and Lu are pretending to have one, too.

Singer/songwriter Joris Buchholz gives a great live performance of his song "Herz über Kopf" ("Heart over head") as a duet for the German radio station ffn.

Here is the music video for "Er," a song by singer-songwriter Joris.

With the song "Du," Joris presents a hymn to the sometimes most difficult, but also most beautiful and longest relationship: one's own relationship with life itself. The song has great lyrics and a joyful melody.

Singer-songwriter Joris wrote his debut song, "Bis ans Ende der Welt" ("Until the End of the World"), for his best friend, who lost his father to cancer. While the lyrics are melancholy, Joris also hopes to highlight the positive things in life.

“Just the Music” is full of sassy optimism! In the lyrics, songwriter Joris is grateful for the music in his head that keeps him from feeling down about life.
