An very very old man lives with his very old cat, his old old goldfish and his old dog on a houseboat, until one day the wolf Cuthbert Q Divine knocks on the door...
The goldfish Märta Proppmätt (Meaty Märta) has a tendency to end up in situations where her hunger forces her to a dilemma. When the aquarium where she lives gets new inhabitants it becomes increasingly hard for Märta to eat and fart her way through life.
