 King Jozef is livid Prieel makes too little effort at his lessons on receiving high-placed visitors. Suddenly the Grimms report the Vidikooks are in the land again, an amusing sight as these tramps always agree (saying "vind ik ook", Dutch for  I think so too ) and carry out silly ideas one of them launches, but then they hear the bunch is charging the castle. Princess Prieel is fed up Kulderzipken allways kindly does as the king asks, and even tells queen Angina, who makes little progress on her trombone and assures her daughter she can act as she wants once she really is queen, she even doubts whether she still wants to marry the  sissy  boy and starts writing down an endless list of requirements for her fiancé. The king commands the Grimms during the cheerful defense of the castle, but after some absurd  methods  by the Vindikooks Jozef stupidly throws his key ring at them, so the castle is invaded by the all too impulsive bunch: the court is at their mercy. Kulderzipken was about to leave as Prieeltje ignores him, but when he notices the invaders rushes to help her; he is also captured but manipulates the Vindikooks simply by using phrases starting with their key expression  I think , and thus gets them out. Gratefully Prieel embraces him again and everybody celebrates.
