The evil Basilisk has changed Skierek and Zagiewka into plaster figurines. To break his spell a deplastinator, a magical mixture is needed. The ingredients of the mixture are in the possession of magical beasts living in various European countries. Oświrek, Pikulik and the good witch Babujaga set off to search for these magical components but at the same time they must beware of the evil Basilisk.

The first stage of the journey on a stormy cloud is the area of the Karkonosze mountains, where Oświrek and Pikulik want to get a strand of hair from the spirit of the mountains Ribesal. At the same time Franek is looking for the treasures of Ribesal. The gnomes are not aware of the fact that Basilisk is following their every step.

Oświrek, Pikulik and Babujaga fly to Prague the capital of the Czech Republic. Here they have to find the magical looking glass that belong to the gnomes many centuries ago. In the Hradčany castle they find a gnome named Vashka and Honza who came with a school field trip of the science club. No one notices that Basilisk has followed them in a toy plane.

The following ingredient of the deplastinator which is to break the spell that was cast on the gnomes is the scale of a niska. A niska is a water demon that has a fish tail. These fish tales are capable of dragging humans into the water deep. The gnomes find these niskas in a mountain river in the German Alps. Basilisk tries to folly Oswirek’s and Pukulik’s attempt to get the scale.
