Juf Roos: Op reis naar de regenboog.

Ms. Roos and Gijs are going on vacation and they're really looking forward to it. The packed lunches are made, the suitcases are packed... the journey can begin! But then something goes wrong. Gijs accidentally knocks the red rose off the teacher's dress, causing it to lose its magic. A big problem, because with the special dress, they could travel anywhere, and now that's no longer possible. Luckily, Ms. Roos and Gijs find a solution in Grandma Rosalinde's chest. If they collect all the colors of the rainbow, they can recreate the dress. It turns out to be quite a quest to find the right colors, but a very fun one!
