She's back - the lovable little elf who sleeps in a matchbox on the artist's desk: and of course her playmates, too, the comical mouse couple Fredrik and Ingolf. The trio are moving into the city. It's a mjor step for Circleen and the mice, and one which has its pros and cons. The city is a dangerous place, but it also has cute, amusing, cheeky playmates such as Sidse, whose family boasts a pirate, and Hassan's family, who introduce food-loving Ingolf to feta cheese and belly-dancing.

Circleen the elf girl and her comical mouse pals, Ingolf and Frederik, live under the geraniums on an artist's balcony. Their idyllic lives are interrupted when they meet the myopic Cindermouse, whose grumpy dad refuses to hold her birthday and instead locks her up in a box. Short, plump, cheese-loving Ingolf is forced to act and to show that he is a real hero.
