Hanne, Marthe and Julia have the vacation of a lifetime in the coastal village of Porto Sirento. But when a mysterious spell turns the girls into beautiful mermaids, their holiday is turned upside down. The inhabitants see mermaids as monsters, so they have to avoid water at all costs! But that is easier said than done..
Also this year, Sinterklaas and his Zwarte Pieten will once again turn the Sportpaleis upside down with the one and only Grand Sinterklaas show. It promises to be one big party with all your Studio 100 friends. You should definitely be there! This year, Campus 12, known from the new Ketnet series, will be featured for the first time during this unforgettable show. Fans will be able to see the cast perform with a 12-member choir for the first time. Campus 12 will perform some songs from their new album. In addition to Campus 12, there are many familiar Studio 100 heroes to admire. Hanne, Klaasje and Marthe from K3 and Mega Mindy are back. But the Night Watch, Samson and Gert, Piet Piraat and Kabouter Plop also welcome Sinterklaas. So it promises to be another unique party with a spectacular performance by Baba Yega as the grand finale!
