Moomin, Sniff and My set out to stop a comet approaching the Moomin valley. Along the way they meet Snusmumriken, the beautiful Snorkfröken, Snorken and a Hemul, who join them in their quest.
Sid and Jean want to buy Mike a nice gift for his 20th birthday, but Mike wants a party at their house. Unfortunately for Sid and Jean, they aren't invited. So they decide to spend the night in the greenhouse so they can spy on the party.
Sid gets a new secretary, and much to Jean's annoyance he keeps coming in late. Also, he is off with his secretary to Birmingham for something work-related. It's OK though, because she is frumpy, and the size of a Green Line bus. Or is she?
It's Sunday, and Sid wants a day of rest, but with the sink blocking, and Mike creating his sculpture, a day of rest is the last thing he's going to get. Jean and Sid meet their new neighbors.
