During December the HNF robots become robot St. Nicholases, dressing as the saint. Robot Pepper St. Nicholas sings a song about Nicholas and tells a bit about his life story and asks children to recite a poem. He has treats for children, too, of course: sweets and a little book about St. Nicholas. The second robot, Peter, is larger and rolls on wheels on the museum's second floor. He has gifts for children in his backpack. Peter speaks in both German and English and tells the story of St. Nicholas, too.
