A number of the educational segments have also dealt with difficult topics, such as life in Germany in the aftermath of World War II, the Chernobyl nuclear disaster and death. Care is taken to explain things in a way that is comprehensible to young children. Analogies are used to explain concepts, and often everyday items already known to most children are used to illustrate. For example, a segment on the Battle of the Teutoburg Forest was produced using Playmobil figures to represent the three Roman legions involved, a total of 16,500 soldiers. Wanting to convey how large a force that was, the program purchased 16,500 Playmobil toy figures and dressed them up as Roman soldiers, lining them up into columns as they would have appeared in real life. The columns of toy soldiers took up 200 meters. These toy Roman legions are now housed in three museums in different parts of Germany.
