In the Moominpappa Grey Moomin mug from the Moomin Classics collection, Moominpappa prepares the Moominhouse for the winter so the family stays warm during their hibernation. The cold stays outside and the warm inside when the windows are insulated with boards, and there's enough firewood. Often longing for adventures and telling stories about the courageous travels of his youth, Moominpappa is also a dedicated family moomin who always does his best to take care of his duties.
