S1·E17 A Change of Air

Bored stiff with calm, sunny weather and stuck in his memoirs, Moominpappa craves adventure. Stinky decides to comply and provides a set of gigantic footsteps, leading up from the sea to Moominhouse. This creates a diversion, but is not enough and Moominpappa decides he and Moominmamma should elope (they never did it before because they had no one to elope from). Stealing off in the middle of the night they leave Moomin to fend for himself, something he doesn't manage all that well. Sniff and Little My help him cook and it is probably a very good thing that his parents haven't managed to get very far...
