Movies
The only known movie title is Princess Perky and the Tower of Trolls. In the movie, Princess Perky is trapped in a tower by two trolls, who are trying to take her tiara. Her only way to escape is to make a rainbow using the tiara.

This movie is D.W.'s favorite of the series. She knows the song that Princess Perky sings by heart. Is it a curse? Is it bad luck? This perky princess keeps getting stuck Captured by villains who want my tiara with powers (Hey, wait! You're a magical crown.) I'll make a rainbow so I can slide down So maybe one day I will learn to steer clear of towers
