Otolo also wrote two follow-up books about the boy scouts Templars, "Der Junge und die Tempelritter" and "Tempelritter auf der Flucht". He inspires the boys with the ideals of scouting, teaches them the appropriate skills and a comprehensive range of songs, and goes on adventurous journeys with them. This results in trip reports, written by himself and illustrated by him in the usual manner as an artist. Such a trip report was used to create this genuinely-lived adventure book "Templars on Trek".
