You know it's cold in Zehland when the polar bears come to visit. They appear out of the Far North in the deep of winter and stay only as long as the weather is frigid.
Last week, the temperature was so low that it felt Arctic. So Ferdinand and Nina decided to build an igloo. They had studied all about the Arctic in school. Ferdinand had done a presentation on how to build igloos for his project and Nina had made some native Inuit costumes for hers. So they felt prepared. Nina pulled out her faux fur boots and parkas to keep them warm while they got to work.
