Moomin and Little My have finally settled into their wintry existence, living on Too-ticki's fish soup and Moominmamma's jam, of which there fortunately is an awful lot. One day, Mr. Brisk arrives, a very hearty and jovial person, who likes cold baths and roughing it in igloo's. He is much taken with Sorry-oo, a very timid dog who only dreams of running with the wolves that are nightly heard howling in Lonely Mountains. He considers them his brothers, but unfortunately they don't... Mr. Brisk finally leaves, having consumed the last jar of his (and Moomin's) favorite jam. (thetvdb.com)
