Once upon a time, the Mucklas could be found everywhere. But in an increasingly tidy world, the cheerful goblins have a hard time, since they love disorder more than anything. Soon the last tribe will have to leave their home. For generations, the little creatures have made themselves at home unnoticed in Hansson's old, chaotic grocer's store. In the wonderful mess, they find everything they need to live, tinker and make mischief. But Hansson's successor, Karl the exterminator, turns the paradise into a tiled and sterile nightmare. So Svunja, Tjorben and Smartö set off on a dangerous search for the promised land. The great adventure begins

Findus promises the chickens to build a feather care machine.

The old man Petterson is trying to sleep but his cat Findus is keeping him awake, so they both agree that Findus shall have his own house.

Pettson and Findus find themselves snowed in their house. The little cat is scared that Christmas is ruined, but Pettson promises that they will celebrate "the best Christmas ever".

Old farmer Pesonen gets a kitten from his neighbour Mrs Kosonen and calls the cat Viiru. When Viiru starts to talk, the two become inseparable friends.

A swimming machine turns up that has been doctored and modified into a tile thrower, but the machine malfunctions and causes an accident that imparts Pettson with amnesia. Suddenly, it seems as though the only hope for Pettson lies in old stories that will jog his memory, such as the tale about Findus getting lost as a kitten and the one about Pettson and Findus embarking on a thrilling treasure hunt.

Pettson and Findus are fishing down by the lake when suddenly a snowstorm rises and it starts to get dark. Lost in the bad weather they are forced to seek shelter in an igloo they build out of blocks of frozen fishes. Inside they tell stories from the past year to keep their spirits up.
