Nils Karlsson Pyssling

Bertil, played by Oskar Löfkvist, befriends Nils Karlsson-Däumling, a tiny pixie played by Jonatan Lindoff, who lives in a mouse hole under his bed. Nils teaches Bertil a magic spell to shrink down and share wondrous adventures in his secret world. However, their idyllic fun is threatened by the sinister rat Schofeline, forcing Bertil to summon all his newfound courage with the help of his parents, Pappa (Charlie Elvegård) and Mamma (Britta Pettersson).
