At the farm, everything is as usual. Only Mama Moo has come up with something unusual again: together with the farmer's daughter Lina, she is going to the pool. Why not, after all, she loves everything new. Her friend the crow Krax is puzzled because cows don’t go to the pool, plus it’s wet there! But Mama Moo won’t be stopped — and soon she is enjoying water activities: diving, sliding down the slide, and steaming in the sauna. She even receives an award for swimming 25 meters. Upon returning to the farm, she tells Krax about her achievements, but he is sad because he can't swim. Then Mama Moo and Lina arrange a contest for the crow, and Krax gets the deserved prize.
